interface (uart) mode this mode enables full-duplex operation wherein one byte of data is transmitted and received after the start bit. the on-chip dedicated uart baud rate generator enables communication using a wide range of selectable baud rates. in addition, a baud rate can also be defined by dividing the clock input to the asck0 pin. the dedicated uart baud rate generator can also be

serial i/o mode. 3-wire serial i/o mode (fixed as msb first) this is an 8-bit data transfer mode using three lines: serial clock line (sck3n), serial output line (so3n), and serial input line (si3n). since simultaneous transmit and receive operations are available in the 3-wire serial i/o mode, the processing time for data transfer is reduced. the first bit in 8-bit data in the serial transfer is fixed as msb. the 3-wire serial i/o mode is useful for connection to a peripheral i/o device that includes a clocked serial interface, a display controller, etc. remark n = 0, 1 figure 4-13. block

interface iic0 the serial interface iic0 has the i 2 c (inter ic) bus mode (multimaster supported). i 2 c bus mode (multimaster supported) this is an 8-bit data transfer mode between multiple devices using two lines: serial clock line (scl0) and serial data bus line (sda0). this mode complies with the i 2 c bus format, and can output ?start condition?, ?data?, and ?stop condition? during transmission via the serial data bus. these data are automatically detected by hardware during reception. since the scl0 and sda0 are open-drain outputs in iic0, pull-up resistors for the serial clock line and the serial data bus line are required. figure 4-15. block diagram of serial interface iic0 msts0 ald0 exc0 coi0 trc0 cld0 dad0 smc0 dfc0 cl01 cl00 ackd0 std0 spd0 iice0 lrel0 wrel0 spie0

are available for further reduction of system current consumption. halt mode: in this mode, the cpu operation clock is stopped. the average current consumption can be reduced by intermittent operation by combining this mode with the normal operation mode. stop mode: in this mode, oscillation of the system clock is stopped. all the operations performed on the system clock are suspended, resulting in extremely small current consumption. figure 6-1. standby function 7 . reset function the following two reset methods are available. external reset by reset signal input internal reset by watchdog
