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.
Table 10-2.
CCON Register
CCON - PCA Counter Control Register (D8h)
Reset Value = 000X 0000b
Not bit addressable
The watchdog timer function is implemented in module 4 (see Figure 10-4).
The PCA interrupt system is shown in Figure 10-2.

Description
7CF
PCA Counter Overflow flag
Set by hardware when the counter rolls over. CF flags an interrupt if bit ECF in CMOD is
set. CF may be set by either hardware or software but can only be cleared by software.
6CR
PCA Counter Run control bit
Must be cleared by software to turn the PCA counter off.
Set by software to turn the PCA counter on.
5-
Reserved
The value read from this bit is indeterminate. Do not set this bit.
4CCF4
PCA Module 4 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
3CCF3
PCA Module 3 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
2CCF2
PCA Module 2 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
1CCF1
PCA Module 1 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
0CCF0
PCA Module 0 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
