Timer Control Register V1 (TCRV1)
TCRV1 is an 8-bit read/write register that selects the valid edge at the TRGV pin, enables TRGV
input, and selects the clock input to TCNTV.
TCRV1 is initialized to H'E2 upon reset and in watch mode, subsleep mode, and subactive mode.
Bits 7 to 5 Reserved Bits: Bit 7 to 5 are reserved; they are always read as 1, and cannot be
modified.
Bits 4 and 3 TRGV Input Edge Select (TVEG1, TVEG0): Bits 4 and 3 select the TRGV input
edge.

Bit 2 TRGV Input Enable (TRGE): Bit 2 enables TCNTV counting to be triggered by input at
the TRGV pin, and enables TCNTV counting to be halted when TCNTV is cleared by compare
match. TCNTV stops counting when TRGE is set to 1, then starts counting when the edge selected
by bits TVEG1 and TVEG0 is input at the TRGV pin.

Bit 1 Reserved Bit: Bit 1 is reserved; it is always read as 1, and cannot be modified.
Bit 0 Internal Clock Select 0 (ICKS0): Bit 0 and bits CKS2 to CKS0 in TCRV0 select the
TCNTV clock source. For details see section 9.4.2, Register Descriptions.
