GPTM Timer B Match (GPTMTBMATCHR)
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. Note that in edge-count mode, when executing an up-count, the value of GPTMTnPR and GPTMTnILR must be greater than the value of GPTMTnPMR and GPTMTnMATCHR.
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.
GPTMTBMATCHR is shown in Figure 18-21 and described in Table 18-24.
