Timer Interrupt Enable Register (TIER)
TIER is an 8-bit read/write register that enables or disables interrupt requests.
TIER is initialized to H'01 upon reset and in standby mode, watch mode, subsleep mode, and
subactive mode.
Bit 7 Input Capture Interrupt A Enable (ICIAE): Bit 7 enables or disables the ICIA interrupt
requested when ICFA is set to 1 in TCSRX.
