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
0001H
. In Compare mode, these
two bytes form the 16-bit Compare value.
Timer 0-1 PWM High and Low Byte Registers
The Timer 0-1 PWM High and Low Byte (TxPWMH and TxPWML) registers (Tables
control Pulse-Width Modulator (PWM) operations. These registers also
store the Capture values for the CAPTURE and CAPTURE/COMPARE modes.
