8.3 Compare/Capture Modules
Each PCA module has an associated SFR with it. These
registers are: CCAPM0 for module 0, CCAPM1 for module
ister (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 mod-
ule 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 mod-
ule’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) deter-
mine 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 8-5
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 regis-
ters 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 8-1.
