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 by a reset or standby mode to H'F8 or H'78. Each ITU
channel has one TIER (table 10.10).

Setting condition:
• GRB is functioning as an output compare register and TCNT = GRB
• GRB is functioning as an input capture register and the value of
Description
Read IMFA when IMFA = 1, then write 0 in IMFA (initial value).
Clearing condition: DMAC is activated by an IMIA interrupt (only
channels 0–3)
Setting condition:
• GRA is functions as an output compare register and TCNT = GRA
• GRA is functioning as an input capture register and the value of
TCNT is transferred to GRB by an input capture signal
TCNT is transferred to GRA by an input capture signal
Function
The TIER controls interrupt enable/disable.
