8-bit Timer Synchronous Output

Operation

When the binary counter of the timer reaches the set value of the compare register, the latched data is

output from port 6 at the next count clock.

Synchronous Output Operation by 8-bit timer (Timer 1, Timer 5)

The port 6 latched data is output from the output pin at the interrupt request generation by the match of the

binary counter and the compare register.

Only port 6 can perform synchronous output operation, and individual pins can be set. 8-bit timers that have

synchronous output operation are timer 1 and timer 5.

Count Timing of Synchronous Output (Timer 1, Timer 5)

The port 6 latched data is output from the output pin in synchronization with the interrupt request

generation by the match of binary counter and compare register.
