The TIER registers are 8-bit registers that control enabling or disabling of interrupt requests for
each channel. The TPU has six TIER registers, one for each channel. The TIER registers are
initialized to H'40 by a reset and in hardware standby mode.
Bit 7—A/D Conversion Start Request Enable (TTGE): Enables or disables generation of A/D
conversion start requests by TGRA input capture/compare match.
Bit 7
TTGE Description
0 A/D conversion start request generation disabled (Initial value)
1 A/D conversion start request generation enabled
Bit 6—Reserved: This bit cannot be modified and is always read as 1.
