Timer Module
15.3.2
Each TRR holds a 16-bit reference value that is compared with the free-running TCN as part of the output
compare function. A match occurs when TCN increments to equal TRR.
15.3.3
Each TCAP is used to latch the TCN value during a capture operation when an edge occurs on the
respective TIN0, TIN1, UART0_RxD, or UART1_RxD, as programmed in TMRn.
15.3.4
TCN registers are 16-bit up counters. Reading a TCNn gives the current counter value without affecting
counting. A write cycle to a TCN register causes it to be cleared.
