Compare Timer 1 Period Registers
The Compare Timer 1 period registers CCPH and CCPL store the 16-bit value for the
Compare Timer 1 count period. CCPH holds the high byte of the 16-bit period value and
CCPL holds the low byte. If CCPH/CCPL is written, shadow latches are always loaded.
The contents of these shadow latches are transferred to the real registers when STE1 is
set and the Compare Timer 1 reaches its period value (operating mode 0) or count value
0000_H (operating mode 1). When the Compare Timer 1 period registers are read,
shadow latches are always accessed.
