Hardware Functions
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/2
Serial interface:
A/D converter:
10 bits x 8 channels
LED driver function:8 pins
Ports:
I/O ports
Input ports
Number of pins with dual function for A/D input:
Operation mode input pin:
Reset input pin:
Operation modes: NORMAL mode
SLOW mode*
HALT mode
STOP mode
and switches operating clock*
Package:
42-SDIP, 44-QFP, 48-QFH
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*
XIOat 32kHz, can be set to measure one minute intervals*
Can operate independently as timer 5 (8-bit timer).
Watchdog timer
Selected by the mask option as fs/2
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.
25 ports (8 have dual functions)*
LED (large current) driver ports:
8 ports (push-pull configuration)
11 ports (all have dual functions) *
Number of pins with dual function for external interrupts: 3*
(One of which can also be used for zero-cross input.)
