16-bit Timer Synchronous Output
7-8 16-bit Timer Synchronous Output
7-8-1 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 16-bit Timer (Timer 7)
The port 6 latched data is output from the output pin at the interrupt request generation by the match of the
binary counter (TM7OC1) or by the full count overflow.
Only port 6 can perform synchronous output operation, and individual pins can be set.
Count Timing of Synchronous Output (Timer 7)
The port 6 latched data is output from the output pin in synchronization with the interrupt request
generation by the match of a binary counter and a compare register 1.
