10.2.4
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 6—Reserved: This bit cannot be modified and is always read as 1.
Bit 5—Underflow Interrupt Enable (TCIEU): Enables or disables interrupt requests (TCIU) by the TCFU flag when
the TCFU flag in TSR is set to 1 in channels 1 and 2.
In channels 0 and 3, bit 5 is reserved. It is always read as 0 and cannot be modified.
