Register 12: GPTM Timer B Match (GPTMTBMATCHR), offset 0x034
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 GPTMTBILR, determines how many edge events are
counted. The total number of edge events counted is equal to the value in GPTMTBILR minus this
value.
In PWM mode, this value along with GPTMTBILR, determines the duty cycle of the output PWM
signal.
When a GPTM is configured to one of the 32-bit modes, the contents of bits 15:0 in this register are
loaded into the upper 16 bits of the GPTMTAMATCHR register. Reads from this register return the
current match value of Timer B and writes are ignored. In a 16-bit mode, bits 15:0 are used for the
match value. Bits 31:16 are reserved in both cases.
GPTM Timer B Match (GPTMTBMATCHR)
Timer 0 base: 0x4003.0000
Timer 1 base: 0x4003.1000
Timer 2 base: 0x4003.2000
Timer 3 base: 0x4003.3000
Offset 0x034
