using standby halt mode the LC6529N/f/l features a convenient halt mode that reduces current drain while the chip is on standby. these standby functions involve the use of one instruction (halt) and two control signal pins (pa3 and res). for the functions to work properly, the design of external circuits and chip software must pay due attention to these three. depending on how extensively the standby functions are used, the designer must consider and provide countermeasures that protect the design from the effects of power supply fluctuations, power interruptions, external noise, and other adverse conditions. this document discusses the circuit and program design issues related to the most frequent application of the standby functions, the detection and recovery from power outages. when using the standby functions, follow the sample circuits given in this document and carefully observe all warnings accompanying them. departures from the design guidelines herein will warrant thorough testing and evaluation of the effects of such sudden changes in the operating environment as momentary power outages on application operation. 1. entering and leaving the halt mode table 1 gives the conditions for entering and leaving the halt mode. table 1 entering and leaving the halt mode note: the second method for leaving the halt mode is only available when the design uses an rc oscillator circuit. it may not work pr operly with a ceramic oscillator circuit. 2. important notes using the standby functions requires close attention to the following issues in application circuit and software design. the power supply voltage must not fall below the rating while the chip is on standby. carefully observe all timing restrictions for the control signals during transitions to and from the halt mode. make sure that a signal for leaving the halt mode does not overlap the execution of the halt instruction. this document demonstrates how to observe these restrictions by discussing both application circuits for a power failure recovery function and programming considerations. such a power failure recovery function detects failure of the main power supply and causes the chip to execute a halt instruction to put itself on standby. reducing the current drain this way allows the backup capacitor to maintain the register contents for a longer period than otherwise possible. when the power is restored, the chip is reset and automatically resumes execution with the program counter set to 000h. the following examples discuss how the software can then distinguish this type of reset from a power on reset sequence along with issues related to dealing with momentary ac power outages. example 1 the first example does not distinguish a power-on reset sequence from a reset trigger by a power failure. circuit diagram figure 2-1 gives the circuit diagram for this sample circuit. no. 5117- 33 /39 LC6529N, lc6529f, lc6529l entering halt mode leaving halt mode halt instruction while pa3 is high. 1. reset signal (res pin pulled low.) 2. pa3 pulled low.
note: all ports other than pa3 are configured as normal input ports. figure 2-1 power outage backup example 1 waveforms during operation figure 2-2 gives the waveforms relevant to the operation of the above circuit. there are three main states: (a) power-on reset sequence, (b) momentary break in main power supply, and (c) recovery from power outage backup state. note: v + tron = v + level at which transistor switches on and off figure 2-2 waveforms relevant to operation of circuit example 1 no. 5117- 34 /39 LC6529N, lc6529f, lc6529l unit (resistance: )
main circuit states a: power-on reset sequence once the power supply voltage has reached the proper level, the chip automatically resets and begins execution with the program counter set to 000 h . caution: this circuit does not reset the chip until the power supply voltage is within the range specified for v dd , so leaves the chip in an indeterminate state. b: momentary break in main power supply i. if only the res pin and none of the pxx pins drops below the threshold level v il , the chip resets and repeats the power-on reset sequence. ii. if the res pin and the pxx pins remain above the threshold level v il , the chip continues normal execution. iii. if both the res pin and the pxx pins drop below the threshold level v il , the chip resets if two consecutive polls fail to detect a low at pxx or, if a low is found, enters the halt mode and then, because the power has been restored, leaves the halt mode. c: recovery from power outage backup state since the power has been restored, the chip leaves the halt mode. design considerations a: v + rise time and c2 the v + rise time must be approximately ten times the rc constant for the reset circuit, c2 r, where r is the internal resistance (typ. 200 k ). it must also be no longer than approximately 20 ms. b: r1 and c1 values r1 must be as small as possible; c1, as large as possible to provide the longest backup time. at the same time, however, r1 must be large enough such that the c1 charging current does not exceed the power supply capacity. c: r2 and r3 values choose these to make the pxx high levels equal to v dd . d: r4 value select r4 and thus the rc constant for c2 and r4 so that c2 discharges sometime in the interval between the point at which v + falls below v + tron (turning off the transistor) and the point at which pxx falls below v il . (otherwise, the chip will enter the halt mode and then not respond to a reset.) e: r5 and r6 values select r5 and r6 so that v + when the reset circuit operates, switching on the transistor (that is, when r5 and r6 produce a v be of approximately 0.6 v) is at least the minimum operating voltage (v dd ) plus the v f for diode d1. to provide a rapid reset once the power is restored, however, keep this voltage as small as possible while still satisfying these conditions. f: calculating backup time from the time that the chip detects the power outage at pxx until it executes the halt instruction, the chip operates normally so drains relatively large amounts of current. c1 must therefore be large enough to provide backup power not only for the set's backup period, but for this transitional period as well. software considerations a: assign signals so that pa3 is maintained high during standby operation. b: the software should double-check a standby request by polling twice. example: bp1 aaa : poll once bp1 aaa : poll twice halt : begin standby operation aaa : no. 5117- 35 /39 LC6529N, lc6529f, lc6529l

main circuit states a: power-on reset sequence the operation and points to watch are the same as for the first example. the only difference is that the software interprets a low at pxx as indicating an initial reset. b: switch to standby operation the chip polls pxx and, if it is low, enters the halt mode. c: recovery from power outage backup state since the power has been restored, the chip leaves the halt mode. if the recovery routine then finds that pxx is high, it switches to a separate routine for restarting after a power outage. caution: if the power supply voltage v dd drops below the v ih level for pxx during the outage, this recovery routine will subsequently find that pxx is low and execute the routine for an initial reset instead. design considerations a: r2 and r3 values make r2 much greater than r1 and choose r3 to limit tr2? i b . b: r4 value since there are no momentary outages, the value is not critical, but select r4 so that c2 quickly discharges. in all other respects, the same considerations apply as in example 1. software considerations a: assign signals so that pa3 is maintained high during standby operation. b: the software should check for a standby request by polling once. example: example 3 the third example adds support for momentary power outages. circuit diagram figure 2-5 gives the circuit diagram for this sample circuit. note: all ports other than pa3 are configured as normal input ports. figure 2-5 power outage backup example 3 bp1 aaa : poll port halt : begin standby operation aaa : no. 5117- 37 /39 LC6529N, lc6529f, lc6529l
