ÂTimers
⢠Timer 0: 16-bit timer/counter with a capture register.
Mode 0: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register) Ã 2 channels
Mode 1: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register)
+ 8-bit counter (with an 8-bit capture register)
Mode 2: 16-bit timer with an 8-bit programmable prescaler (with a 16-bit capture register)
Mode 3: 16-bit counter (with a 16-bit capture register)
⢠Timer 1: 16-bit timer/counter that supports PWM/toggle outputs
Mode 0: 8-bit timer with an 8-bit prescaler (with toggle outputs) + 8-bit timer/
counter with an 8-bit prescaler (with toggle outputs)
Mode 1: 8-bit PWM with an 8-bit prescaler à 2 channels
Mode 2: 16-bit timer/counter with an 8-bit prescaler (with toggle outputs)
(toggle outputs also possible from the lower-order 8 bits)
Mode 3: 16-bit timer with an 8-bit prescaler (with toggle outputs)
(The lower-order 8 bits can be used as PWM)
⢠Timer 6: 8-bit timer with a 6-bit prescaler (with toggle outputs)
⢠Timer 7: 8-bit timer with a 6-bit prescaler (with toggle outputs)
⢠Base timer
1) The clock is selectable from the subclock (32.768kHz crystal oscillation), system clock, and timer 0 prescaler
output.
2) Interrupts are programmable in 5 different time schemes
ÂHigh-Speed Clock Counter
⢠Can count clocks with a maximum clock rate of 20MHz (at a main clock of 10MHz).
⢠Can generate output real time.
ÂSIO
⢠SIO0: 8-bit Synchronous serial interface
1) LSB first/MSB first mode selectable
2) Built-in 8-bit baudrate generator (maximum transfer clock cycle=4/3tCYC)
⢠SIO1: 8-bit asynchronous/synchronous serial interface
Mode 0: Synchronous 8-bit serial I/O (2- or 3-wire configuration, 2 to 512 tCYC transfer clocks)
Mode 1: Asynchronous serial I/O (half-duplex, 8 data bits, 1 stop bit, 8 to 2048 tCYC baudrates)
Mode 2: Bus mode 1 (start bit, 8 data bits, 2 to 512 tCYC transfer clocks)
Mode 3: Bus mode 2 (start detect, 8 data bits, stop detect)
ÂUART
⢠Full Duplex
⢠7/8/9 bit data bits selectable
⢠1 Stop bit (2 bits in continuous data transmission)
⢠Built-in baudrate generator
ÂAD Converter: 12 bits/8 bits à 9 channels
⢠12/8 bits AD converter resolution selectable
