CPU functions

The number of instructions : 340

Instruction bit length : 8 bits, 16 bits

Instruction length : 1 byte to 7 bytes

Data bit length : 1 bit, 8 bits, 16 bits

Minimum execution time : 62.5 ns (at machine clock frequency of 16 MHz)

Interrupt processing time : 1.5 µs

(at machine clock frequency of 16 MHz, minimum value)

UART (3 channels)

Clock synchronized transmission (500 Kbps / 1 Mbps / 2 Mbps)

Clock asynchronized transmission (4808/5208/9615/10417/19230/38460/62500

/500000 bps at machine clock frequency of 16 MHz)

Transmission can be performed by bi-directional serial transmission or by master/

slave connection.

8/10-bit A/D converter

Conversion precision : 8/10-bit can be selectively used.

Number of inputs : 8

One-shot conversion mode (converts selected channel once only)

Scan conversion mode (converts two or more successive channels and can program

up to 8 channels)

Continuous conversion mode (converts selected channel continuously)

Stop conversion mode (converts selected channel and stop operation repeatedly)

8/16-bit PPG timers

(6 channels)

Number of channels : 6 (8/16-bit × 6 channels)

PPG operation of 8-bit or 16-bit

A pulse wave of given intervals and given duty ratios can be output.

Pulse interval : fsys, fsys/21, fsys/22, fsys/23, fsys/24, 128µs

(at oscillation of 4 MHz, fsys = system clock frequency of 16 MHz, fosc = oscillation

clock frequency)

16-bit Reload timer

Number of channels : 2

Operation clock frequency : fsys/21, fsys/23, fsys/25 (fsys = System clock frequency)

Supports External Event Count function
