Bit 2—Buffer Enable B (BUFEB): Selects whether ICRD is to be used as a buffer register for
ICRB.
Bits 1 and 0—Clock Select (CKS1, CKS0): Select external clock input or one of three internal
clock sources for the FRC. External clock pulses are counted on the rising edge of signals input to
the external clock input pin (FTCI).
11.2.9
TOCR is an 8-bit readable/writable register that enables output from the output compare pins,
selects the output levels, switches access between output compare registers A and B, controls the
ICRD and OCRA operating mode, and switches access to input capture registers A, B, and C.
TOCR is initialized to H'00 by a reset and in hardware standby mode.
Bit 7—Input Capture D Mode Select (ICRDMS): Specifies whether ICRD is used in the normal
operating mode or in the operating mode using OCRDM.
