Chapter 1 Overview

Timers 2 and 3 can be cascaded.
Timer 4 16-bit timer
Square wave output, 16-bit PWM output are possible.
Clock source: fosc, fs/4, fs/16, TM4IO pin input
Input capture function
Time base timer
Clock source: fosc, fs/4, fx*4, fx/2
13
*4or fosc/213
XIOat 32kHz, can be set to measure one minute intervals*4
Can operate independently as timer 5 (8-bit timer).
Watchdog timer
Selected by the mask option as fs/216, fs/218, or fs/220
Remote control Based on the timer output, a remote control carrier with duty ratio
carrier output: of 1/2, 1/3 can be output.
Buzzer output: Output frequency can be selected from fs/29, fs/210, fs/211 or fs/212.
Serial interface: Synchronous/ Simple UART (half-duplex)
Transfer clock: fs/2, fs/4, fs/16, 1/2 of timer 3 output
When using timer 3, the transfer rates for a 12MHz
oscillation are 19200/9600/4800/2400/1200/300 bps.
MSB or LSB can be selected as the first bit for transfer. An
arbitrary transfer size of 1 to 8 bits can be selected.
A/D converter: 10 bits x 8 channels
LED driver function:8 pins
Ports: I/O ports 25 ports (8 have dual functions)*5
LED (large current) driver ports:
8 ports (push-pull configuration)
Input ports 11 ports (all have dual functions) *6
Number of pins with dual function for external interrupts: 3*7
(One of which can also be used for zero-cross input.)
Number of pins with dual function for A/D input: 8
Operation mode input pin: 1
Reset input pin: 1
Operation modes: NORMAL mode
SLOW mode*4
HALT mode
STOP mode
and switches operating clock*4
