TH and TL—Timer High and Low Bytes
These 2 bytes, {TMRH[7:0], TMRL[7:0]}, contain the current 16-bit timer count value.
The Timer 0–1 Reload High and Low Byte (TxRH and TxRL) Registers
16-bit reload value, {TRH[7:0], TRL[7:0]}. Values written to the Timer 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
maximum count value which initiates a timer reload to
two bytes form the 16-bit Compare value.
The Timer 0–1 PWM High and Low Byte (TxPWMH and TxPWML) registers
and
store the Capture values for the CAPTURE and CAPTURE/COMPARE modes.
