Description
Load Value. The up or down counter is periodically loaded with this value if periodic mode is selected
(CON0, Bit 3 = 1). LD0 writes during up or down counter timeout events are delayed until the event has
passed.
Description
Current Count. Reflects the current up or down counter value. Value delayed two PCLK cycles due to
clock synchronizers.
Description
Synchronization Bypass. Used to bypass the synchronization logic within the block. Use only with
synchronous clocks. This bit field also changes the CON0, Bits[1:0] maximum prescaler count from 3 to 0.
Counter and Prescale Reset Enable. Used to enable and disable the reset feature. Used in conjunction
with the EVTEN and EVENT select range. When a selected event occurs, the 16-bit counter and 8-bit
prescale are reset. This reset is required in PWM demodulation mode.
Event Select. Used to enable and disable the capture of events. Used in conjunction with the event
select range. When a selected event occurs, the current value of the up or down counter is captured in
GPTx_CAPTURE.
0 Events are not captured.
1 Events are captured.
Event Select Range. Timer event select range (0 to 31).
Reload Control. This bit is only used for periodic mode. This bit allows the user to select whether the up or
down counter is reset only on a timeout event or when CLRI0, Bit 0 is set.
1 Resets the up or down counter when the clear timeout interrupt bit is set.
0 Up or down counter is only reset on a timeout event.
Clock Select. Used to select a timer clock from the four available clock sources.
00 AFE PCLK.
01 AFE high-power oscillator.
10 AFE low frequency oscillator.
11 External clock.
Timer Enable. Used to enable and disable the timer. Clearing this bit resets the timer, including the VAL0
register.
0 Timer is disabled. Default.
1 Timer is enabled.
Timer Mode. This bit is used to control whether the timer runs in periodic or free running mode. In periodic
mode, the up or down counter starts at the defined load value. In free running mode, the up or down
counter starts at 0x0000 or 0xFFFF, depending on whether the timer is counting up or down.
1 Timer runs in periodic mode. Default.
0 Timer runs in free running mode.
