Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Compare Match Timer Counter Size
Selects whether the compare match timer counter
(CMCNT) is used as a 16-bit counter or a 32-bit counter.
This setting becomes the valid size for the compare
match timer constant register (CMCOR).
0: Operates as a 32-bit counter
1: Operates as a 16-bit counter
Compare Match Mode
Selects one-shot operation or free-running operation of
the counter.
0: One-shot operation
1: Free-running operation
Reserved
These bits are always read as 0. The write value should
always be 0.
Compare Match Request
Selects enable or disable for a DMA transfer request or
internal interrupt request in a compare match.
00: Disables a DMA transfer request and internal
01: Enables DMA transfer request
10: Enables an internal interrupt request
11: Setting prohibited
Reserved
This bit is always read as 0. The write value should
always be 0.
