■
LCD controller
Seven display modes are available (static, 1/2, 1/3, 1/4 duty × 1/2, 1/3 bias)
Segment output and common output can be switched to general purpose input/output ports.
■
Small signal detection (MIC signals etc)
Counts pulses with the level which is greater than a preset value
2-bit counter
■
Timer
Timer 0 : 16-bit timer/counter with capture register
Mode 0 : 2-channel 8-bit timer 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 function
Mode 0 : 2-channel 8-bit timer/counter (with toggle output)
Mode 1 : 2-channel 8-bit PWM
Mode 2 : 16-bit timer/counter (with toggle output) Toggle output from lower 8-bits is also possible.
Mode 3 : 16-bit timer (with toggle output) Lower order 8-bits can be used as PWM.
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. The clock signal can be selected from any of the following :
Sub-clock (32.768kHz crystal oscillator), system clock, and prescaler output from timer 0
2. Interrupts of five different time intervals are possible.
■
High speed clock counter
Countable up to 20MHz clock (when using 10MHz main clock)
Real time output
