TH and TL—Timer high and low bytes
These 2 bytes, {TH[7:0], TL[7:0]}, contain the current 16-bit timer count value.
The timer 0–1 reload high and low byte (TxRH and TxRL) registers
Table
reload high byte register are stored in a temporary holding register. When a write to the
timer reload low byte register occurs, the temporary holding register value is written to the
timer high byte register. This operation allows simultaneous updates of the 16-bit timer
reload value.
In COMPARE mode, the timer reload high and low byte registers store the 16-bit compare
value.
TRH and TRL—Timer reload register high and low
These two bytes form the 16-bit reload value, {TRH[7:0], TRL[7:0]}. This value sets the
50) store a 16-bit reload value, {TRH[7:0], TRL[7:0]}. Values written to the timer
