A/D Conversion Start Request Enable
Enables or disables generation of A/D conversion start
requests by TGRA input capture/compare match.
0: A/D conversion start request generation disabled
1: A/D conversion start request generation enabled
Reserved
This bit is always read as 1 and cannot be modified.
Underflow Interrupt Enable
Enables or disables interrupt requests (TCU) by the TCFU
flag when the TCFU flag in TSR is set to 1 in channels 1
and 2. In channel 0, bit 5 is reserved.
0: Interrupt requests (TCIU) by TCFU disabled
1: Interrupt requests (TCIU) by TCFU enabled
Overflow Interrupt Enable
Enables or disables interrupt requests (TCIV) by the
TCFV flag when the TCFV flag in TSR is set to 1.
0: Interrupt requests (TCIV) by TCFV disabled
1: Interrupt requests (TCIV) by TCFV enabled
TGR Interrupt Enable D
Enables or disables interrupt requests (TGID) by the
TGFD bit when the TGFD bit in TSR is set to 1 in channel
0. In channels 1 and 2, bit 3 is reserved. It is always read
as 0 and cannot be modified.
0: Interrupt requests (TGID) by TGFD disabled
1: Interrupt requests (TGID) by TGFD enabled.
TGR Interrupt Enable C
Enables or disables interrupt requests (TGIC) by the
TGFC bit when the TGFC bit in TSR is set to 1 in channel
0. In channels 1 and 2, bit 2 is reserved. It is always read
as 0 and cannot be modified.
0: Interrupt requests (TGIC) by TGFC disabled
1: Interrupt requests (TGIC) by TGFC enabled
