PCA Counter/Timer Overflow Flag.
Set by hardware when the PCA Counter/Timer overflows from 0xFFFF to 0x0000.
When the Counter/Timer Overflow (CF) interrupt is enabled, setting this bit causes the
CPU to vector to the PCA interrupt service routine. This bit is not automatically cleared
by hardware and must be cleared by software.
PCA Counter/Timer Run Control.
This bit enables/disables the PCA Counter/Timer.
0: PCA Counter/Timer disabled.
1: PCA Counter/Timer enabled.
Read = 0b, Write = Don't care.
PCA Module 4 Capture/Compare Flag.
This bit is set by hardware when a match or capture occurs. When the CCF4 interrupt
is enabled, setting this bit causes the CPU to vector to the PCA interrupt service rou-
tine. This bit is not automatically cleared by hardware and must be cleared by software.
PCA Module 3Capture/Compare Flag.
This bit is set by hardware when a match or capture occurs. When the CCF3 interrupt
is enabled, setting this bit causes the CPU to vector to the PCA interrupt service rou-
tine. This bit is not automatically cleared by hardware and must be cleared by software.
PCA Module 2 Capture/Compare Flag.
This bit is set by hardware when a match or capture occurs. When the CCF2 interrupt
is enabled, setting this bit causes the CPU to vector to the PCA interrupt service rou-
tine. This bit is not automatically cleared by hardware and must be cleared by software.
PCA Module 1 Capture/Compare Flag.
This bit is set by hardware when a match or capture occurs. When the CCF1 interrupt
is enabled, setting this bit causes the CPU to vector to the PCA interrupt service rou-
tine. This bit is not automatically cleared by hardware and must be cleared by software.
PCA Module 0 Capture/Compare Flag.
This bit is set by hardware when a match or capture occurs. When the CCF0 interrupt
is enabled, setting this bit causes the CPU to vector to the PCA interrupt service rou-
tine. This bit is not automatically cleared by hardware and must be cleared by software.
