10.2.12 Timer Interrupt Enable Register (TIER)
The timer status interrupt enable register (TIER) is an eight-bit read/write register that controls
enabling/disabling of overflow interrupt requests and general register compare match/input capture
interrupt requests. TIER is initialized to H'F8 or H'78 by a reset and in standby mode. Each ITU
channel has one TIER.

Note: * Undefined
Bits 7–3—Reserved: Bit 7 is read as undefined. Bits 6–3 are always read as 1. The write value to
bit 7 should be 0 or 1. The write value to bits 6–3 should always be 1.

Description
Clearing condition:
Read IMFA when IMFA = 1, then write 0 in IMFA
DMAC is activated by an IMIA interrupt (only channels 0–3)
Setting conditions:
GRA is functioning as an output compare register and TCNT = GRA
GRA is functioning as an input capture register and the value of TCNT is
transferred to GRA by an input capture signal
