2/27
Ver.1.00
(3) Minimum Instruction Cycle Time : 300ns (10MHz)
(4) Ports
- Input/output ports
Input/output programmable for each bit individually 43 (P1n, P2n, P70 to P73, P8n, PAn, PBn, PCn)
Data direction programmable in nibble units
- Input ports
- PWM output ports
- Oscillator pins
- Reset pin
- Power supply
(5) Timer
- Timer 0 : 16-bit timer/counter with capture register
Mode 0: Two 8-bit timers with programmable 8-bit prescaler and 8-bit capture register
Mode 1: 8-bit timer with 8-bit programmable prescaler and 8-bit capture register + 8-bit
counter with 8-bit capture register
Mode 2: 16-bit timer with 8-bit programmable prescaler and 16-bit capture register
Mode 3: 16-bit counter with 16-bit capture register
- Timer 1 : PWM/16-bit timer/counter with toggle output
Mode 0: 8-bit timer (with toggle output) + 8-bit timer/counter (with toggle output)
Mode 1: Two 8-bit PWM
Mode 2: 16-bit timer/counter (with toggle output) Toggle output is also possible by using the
lower order 8 bits.
Mode 3: 16 bit timer (with toggle output) The lower order 8 bits can be used as PWM output.
- Timer 4: 8-bit timer with 6-bit prescaler
- Timer 5: 8-bit timer with 6-bit prescaler
- Timer 6: 8-bit timer with 6-bit prescaler
- Timer 7: 8-bit timer with 6-bit prescaler
- Base timer
1. Clock for the base timer is selectable from sub-clock (32.768kHz crystal oscillation), system
clock or programmable prescaler output of timer 0.
2. There can be five separate interrupt sources.
(6) High speed clock counter
1. Maximum of 20MHz possible (when using a 10MHz main clock).
2. Real-time output
(7) Serial interface
- SIO 0: 8 bit synchronous serial interface
1. LSB first/MSB first-function available
2. An internal 8-bit baud-rate generator (maximum transmit clock period 4/3 T
CYC
)
3. Consecutive automatic data communication (1 - 256 bits)
- SIO 1: 8 bit asynchronous/synchronous serial interface
Mode 0: Synchronous 8 bit serial IO (2-wire or 3-wire, transmit clock 2 - 512 T
CYC
)
Mode 1: Asynchronous serial IO (half duplex, 8 data bits, 1 stop bit, baud-rate 8 - 2048 T
CYC
)
Mode 2: Bus mode 1 (start bit, 8 data bits, transmit clock 2 - 512 T
CYC
)
Mode 3: Bus mode 2 (start detection, 8 data bits, stop detection)
8 (P0n)
2 (XT1, XT2)
2 (PWM0, PWM1)
2 (CF1, CF2)
1 (
RES
)
6 (VSS1 to 3, VDD1 to 3)
