Description
Specifies whether ICRD is used in normal operating
mode or in operating mode using OCRDM.
0: Normal operating mode is specified for ICRD
1: Operating mode using OCRDM is specified for ICRD
Output Compare A Mode Select
Specifies whether OCRA is used in normal operating
mode or in operating mode using OCRAR and OCRAF.
0: Normal operating mode is specified for OCRA
1: Operating mode using OCRAR and OCRAF is
Input Capture Register Select
The same addresses are shared by ICRA and OCRAR,
by ICRB and OCRAF, and by ICRC and OCRDM. The
ICRS bit determines which registers are selected when
the shared addresses are read from or written to. The
operation of ICRA, ICRB, and ICRC is not affected.
0: ICRA, ICRB, and ICRC are selected
1: OCRAR, OCRAF, and OCRDM are selected
Input Capture D Mode Select
specified for OCRA
