GPT0 – GPT7 Input and Up/Down Counter Output (GPT_COUNTER)
Registers
Prescale amount applied to internal counter (in IP bus clocks).
Note: The prescale field should be written prior to enabling any timer mode. A prescale of 0x0001 means one
Input
Sets number of prescaled counts applied to reference events, as follows:
OC—Number of prescaled counts counted before creating output event.
PWM—Number of prescaled counts defining the PWM output period.
Internal Timer—Number of prescaled counts counted before the timer expires.
Note: Reading this register only returns the programmed value, intermediate values of the internal counter
Output
IC—When ICM is equal to 01/10/11, reading this field returns the internal up/down counter value.
Note: Internal up/down counter starts at 0. Writing this field has no effect.

IP bus clock per count increment. If prescale is 0 when any timer mode is started, it results in an
effective prescale of 64 KB. The counter immediately begins and an output event occurs with the 64 KB
