(see the control data description for details.) if a key on one of the lines corresponding to a ks1 to ks5 pin wh ich is set high is pressed, t he oscillator on the osc pin is started and a key scan is performed. keys are scanned until all ke ys are released. multiple key presses are recognized by determining whether multiple key data bits are set. if a key is pressed for longer than 9904t(s)(where t=1/fo sc) the bu97600fv-m/bu97600fuv-m outputs a key data read request (a low level on sdo) to the controller. the controller acknowledges this request and reads the key data. however, if sce is high during a serial data transfer, sdo will be set high. after the controller reads the key data, the key dat a read request is cleared (sdo is set high) and the bu97600fv-m/bu97600fuv-m performs another key scan. howeve r, this does not clear sleep mode. also note that sdo, being an open-drain output, requires a pull-up resistor (between 1 k ? and 10k ? ). sleep mode key scan example example: bu0=0, bu1=0, bu2=1 (sleep with only ks5 high) (note23) these diodes are required to reliable recognize multiple key pre sses on the ks5 line when sleep mode state with only ks5 high, as in the above example. that is, these diodes prevent incorrect operations due to sneak currents in the ks5 key scan output signal when keys on the ks1 to ks5 l ines are pressed at the same time. figure 21. key scan operation in sleep mode multiple key presses although the bu97600fv-m/bu97600fuv-m is capable of key scanning wi thout inserting diodes for dual key presses, triple key presses on the ki1 to ki4 input pin lines, or multiple key pre sses on the ks1 to ks5 output pin lines, multiple presses other t han these cases may result in keys that were not pressed recogniz ed as having been pressed. theref ore, a diode must be inserted in series with each key. applications that do not recognize mu ltiple key presses of three or more keys should check the key dat a for three or more 1 bit and ignore such data. when any one of these keys is pressed, the oscillator starts and a keys scan operation is performed. ks1/s23 kl1/s32 kl2/s33 kl3/s34 kl4/s35 ks2/s24 ks5/s27 ks3/s25 ks4/s26 (note23)
