9.4 Operating Timers by External Clock Inputs
Select the external clock(P44/T02P0CK) and timer0 (8-bit mode) in the TM0CON0 register, and input the operation clock for
the Timer 0 from the P44 pin.
9.4.1
9.4.2
When the external clock is selected as the operation clock for the Timer 0 (8-bit timer mode), operate it by inputting the
clock from the P04 or with the P44 set to the 1st function. When the external clock is selected as the operation clock for
the Timer 1 (8-bit timer mode), operate it by inputting the clock with the P45 set to the 1st function. When the external
clock is selected as the operation clock for the Timer 2 (8-bit timer mode), operate it by inputting the clock from the P04
or with the P44 set to the 1st function. When the external clock is selected as the operation clock for the Timer 3 (8-bit
timer mode), operate it by inputting the clock with the P45 set to the 1st function.
When the external clock is selected as the operation clock for the Timers 0 and 1 set to the 16-bit timer mode, operate
them by inputting the clock from the P04. When the external clock is selected as the operation clock for the Timers 2 and
3 set to the 16-bit timer mode, operate them by inputting the clock with the P44 set to the 1st function.
Set the external clock frequency to a value below the operating frequency (fop) in "Appendix C Electrical
Characteristics."
Select the external clock(P04/T02P0CK) and timer0 (8-bit mode) in the TM0CON0 register, And input the operation
clock for the Timer 0 from the P04 pin.
Set the P44MD1 bit (P4MOD1 register's bit 4) to "0" and the P44MD0 bit (P4MOD0 register's bit 4) to "0" for
specifying the P44 to the 1st function.
Set the P43DIR bit (P4DIR register's bit 3) to "1" for specifying the state mode of the P44 pin to input.
