R/W :
The TIER is an 8-bit read/write register that controls permission/prohibition of interrupt requests.
The TIER is initialized to H'00 when reset or under the standby mode, watch mode, subsleep
mode, module stop mode or subactive mode.
Bit 7
Enabling the Input Capture Interrupt A (ICIAE): This bit works to permit/prohibit
interrupt requests (ICIA) by the ICFA when the ICFA of the TCSRX is being set to 1.
Bit 7
ICIAE
Description
0
Prohibits interrupt requests (ICIA) by the ICFA
(Initial value)
1
Permits interrupt requests (ICIA) by the ICFA
Bit 6
Enabling the Input Capture Interrupt B (ICIBE): This bit works to permit/prohibit
interrupt requests (ICIB) by the ICFB when the ICFB of the TCSRX is being set to 1.
Bit 6
ICIBE
Description
0
Prohibits interrupt requests (ICIB) by the ICFB
(Initial value)
1
Permits interrupt requests (ICIB) by the ICFB
Bit 5
Enabling the Input Capture Interrupt C (ICICE): This bit works to permit/prohibit
interrupt requests (ICIC) by the ICFC when the ICFC of the TCSRX is being set to 1.
Bit 5
ICICE
Description
0
Prohibits interrupt requests (ICIC) by the ICFC
(Initial value)
1
Permits interrupt requests (ICIC) by the ICFC
