The CCP (Capture/Compare/PWM) module contains a
16-bit register, which can operate as a 16-bit capture
register, as a 16-bit compare register or as a PWM
master/slave duty cycle register. Table 7-1 shows the
timer resources of the CCP module modes.
Capture/Compare/PWM Register 1 (CCPR1) is com-
prised of two 8-bit registers: CCPR1L (low byte) and
CCPR1H (high byte). The CCP1CON register controls
the operation of CCP1. All are readable and writable.
