Table 11.
CMOD Register
CMOD - PCA Counter Mode Register (D9h)
Reset Value = 00XX X000b
Not bit addressable
The CMOD register includes three additional bits associated with the PCA (see
Figure 11 and Table 11).
The CIDL bit which allows the PCA to stop during idle mode.
The WDTE bit which enables or disables the watchdog function on module 4.
The ECF bit which when set causes an interrupt and the PCA overflow flag CF (in
the CCON SFR) to be set when the PCA timer overflows.
The CCON register contains the run control bit for the PCA and the flags for the PCA
timer (CF) and each module (see Table 12).
Bit CR (CCON.6) must be set by software to run the PCA. The PCA is shut off by
clearing this bit.
Bit CF: The CF bit (CCON.7) is set when the PCA counter overflows and an
interrupt will be generated if the ECF bit in the CMOD register is set. The CF bit can
only be cleared by software.
Bits 0 through 4 are the flags for the modules (bit 0 for module 0, bit 1 for module 1,
etc.) and are set by hardware when either a match or a capture occurs. These flags
can only be cleared by software.
