H8S/2215 Group
Bit Bit Name Initial Value R/W Description
7 ACS3 0 R/W Asynchronous Clock Source Select
Selects the clock source in asynchronous mode
depending on the combination with the ACS2 to ACS0
(bits 2 to 0 in SEMRA_0). For details, see section 13.3.9,
Serial Extended Mode Register (SEMR) (Only for
channel 0 in H8S/2215).
6 to

— Undefined — Reserved
The write value should always be 0.
3 TIOCA2E 1 R/W TIOCA2 Output Enable
Controls the TIOCA2 output on the P16 pin.
When the TIOCA2 in TPU is output to generate the
transfer clock, P16 is used as other function pin by
setting this bit to 0.
0: Disables output of TIOCA2 in TPU
1: Enables output of TIOCA2 in TPU
2 TIOCA1E 1 R/W TIOCA1 Output Enable
Controls the TIOCA1 output on the P14 pin.
When the TIOCA1 in TPU is output to generate the
transfer clock, P14 is used as other function pin by
setting this bit to 0.
0: Disables output of TIOCA1 in TPU
1: Enables output TIOCA1 in TPU
1 TIOCC0E 1 R/W TIOCC0 Output Enable
Controls the TIOCC0 output on the P12 pin.
When the TIOCC0 in TPU is output to generate the
transfer clock, P12 is used as other function pin by
setting this bit to 0.
0: Disables output of TIOCC0 in TPU
1: Enables output of TIOCC0 in TPU
0 TIOCA0E 1 R/W TIOCA0 Output Enable
Controls the TIOCA0 output on the P10 pin.
When the TIOCA0 in TPU is output to generate the
transfer clock, P10 is used as other function pin by
setting this bit to 0.
0: Disables output of TIOCA0 in TPU
1: Enables output of TIOCA0 in TPU
