an interrupt will be generated if the ECF bit in the CMOD register is set. The CF bit can only be cleared
by software. Each module has its own timer interrupt or capture interrupt flag (CCF0 for module 0,
CCF4 for module 4, etc.). They are set when either a match or capture occurs. These flags can only be
cleared by software. (See “PCA Timer/Counter Control Register (CCON)” on page 26.)
Compare/Capture Modules
Each PCA module has an associated SFR with it. These registers are: CCAPM0 for module 0,
CCAPM1 for module 1, etc. Refer to “PCA Compare/Capture Module Mode Register (CCAPMn)” on
page 28 for details. The registers each contain 7 bits which are used to control the mode each module
will operate in. The ECCF bit (CCAPMn.0 where n = 0, 1, 2, 3, or 4 depending on module) will enable
the CCF flag in the CCON SFR to generate an interrupt when a match or compare occurs. PWM
(CCAPMn.1) enables the pulse width modulation mode. The TOG bit (CCAPMn.2) when set, causes
the CEX output associated with the module to toggle when there is a match between the PCA counter
and the module’s capture/compare register. When there is a match between the PCA counter and the
module’s capture/compare register, the MATn (CCAPMn.3) and the CCFn bit in the CCON register to
be set.
Bits CAPN (CCAPMn.4) and CAPP (CCAPMn.5) determine whether the capture input will be active on
a positive edge or negative edge. The CAPN bit enables the negative edge that a capture input will be
active on, and the CAPP bit enables the positive edge. When both bits are set, both edges will be
enabled and a capture will occur for either transition. The last bit in the register ECOM (CCAPMn.6)
when set, enables the comparator function. Table 21 shows the CCAPMn settings for the various PCA
functions.
There are two additional register associated with each of the PCA modules: CCAPnH and CCAPnL.
They are registers that hold the 16-bit count value when a capture occurs or a compare occurs. When
a module is used in PWM mode, these registers are used to control the duty cycle of the output. See
Figure 24.
