(Continued)

11. Serial I/O

• UART × 4 channels. Any of them is capable of serial transfer in sync with clock attached with the LSB/MSB

switching function.

• Serial data output and serial clock output are selectable by push-pull/open drain software.

• A 16-bit timer (U-timer) is contained as a dedicated baud rate generator allowing any baud rate to be generated.

12. I2C Bus Interface

• One channel master/slave send and receive

• Arbitration and clock synchronization functions

(The product is licensed with the Philips I2C patent to support those customers who intend to use this product

in an I2C system in compliance with the standard I2C specification stipulated by Philips.)

13. Clock Switching Function

• Gear function : Operating clock ratios to the basic clock can be set independently for the CPU and peripherals

from four types, 1 : 1, 1 : 2, 1 : 4 or 1 : 8.

14. Clock Function (Calendar Macro)

• Internal 32 kHz clock function

• Capable of operating in clock mode to run only the clock function while the CPU and peripheral macros are

stopped.

15. Interrupt Controller

External interrupt input (16 channels in total) :

• Allows the rising edge/falling edge/H level/L level to be set.

Internal interrupt factors :

• Interrupt by resources and delay interrupt

16. Others

• Reset cause : Power on reset/watchdog timer/software reset/external reset

• Low power consumption mode : Sleep/stop/clock mode

• Package : LQFP 144-pin

• CMOS technology (0.35 µm)

• Power supply voltage : 3.15 V to 3.6 V
