General-Purpose Timers
Register 11: GPTM Timer A Match (GPTMTAMATCHR), offset 0x030
This register is loaded with a match value. Interrupts can be generated when the timer value is equal
to the value in this register in one-shot or periodic mode.
In Edge-Count mode, this register along with GPTMTAILR, determines how many edge events are
counted. The total number of edge events counted is equal to the value in GPTMTAILR minus this
value.
In PWM mode, this value along with GPTMTAILR, determines the duty cycle of the output PWM
signal.
When a GPTM is configured to one of the 32-bit modes, GPTMTAMATCHR appears as a 32-bit
register (the upper 16-bits correspond to the contents of the GPTM Timer B Match
(GPTMTBMATCHR) register). In a 16-bit mode, the upper 16 bits of this register read as 0s and
have no effect on the state of GPTMTBMATCHR.
GPTM Timer A Match (GPTMTAMATCHR)
Timer 0 base: 0x4003.0000
Timer 1 base: 0x4003.1000
Timer 2 base: 0x4003.2000
Timer 3 base: 0x4003.3000
Offset 0x030
Type R/W, reset 0xFFFF.FFFF
