(4) Port 9 function control register (PFC9)
Caution When performing separate address bus output (A0 to A15), set the PMC9 register to FFFFH for all
16 bits at once after clearing the PFC9 or PFCE9 register to 0000H.
After reset: 0000H R/W Address: PFC9 FFFFF472H,
PFC9L FFFFF472H, PFC9H FFFFF473H
PFC97 PFC96 PFC95 PFC94 PFC93 PFC92 PFC91 PFC90
PFC915 PFC914 PFC913 PFC912 PFC911 PFC910 PFC99 PFC98

PFC9 (PFC9H)
(PFC9L)
Remarks 1. For details of alternate function specification, see 4.3.7 (6) Port 9 alternate function
specifications.
2. The PFC9 register can be read or written in 16-bit units.
However, when using the higher 8 bits of the PFC9 register as the PFC9H register and
the lower 8 bits as the PFC9L register, PFC9 can be read or written in 8-bit or 1-bit units.
3. To read/write bits 8 to 15 of the PFC9 register in 8-bit or 1-bit units, specify them as bits 0
to 7 of the PFC9H register.
(5) Port 9 function control expansion register (PFCE9)
Caution When performing separate address bus output (A0 to A15), set the PMC9 register to FFFFH for all
16 bits at once after clearing the PFC9 or PFCE9 register to 0000H.
After reset: 0000H R/W Address: PFCE9 FFFFF712H,
PFCE9L FFFFF712H, PFCE9H FFFFF713H
PFCE97 PFCE96 PFCE95 PFCE94 PFCE93 PFCE92 PFCE91 PFCE90
PFCE915 PFCE914 0 0 0 0 0 0

PFCE9 (PFCE9H)
(PFCE9L)
Remarks 1. For details of alternate function specification, see 4.3.7 (6) Port 9 alternate function
specifications.
2. The PFCE9 register can be read or written in 16-bit units.
However, when using the higher 8 bits of the PFCE9 register as the PFCE9H register
and the lower 8 bits as the PFCE9L register, PFCE9 can be read or written in 8-bit or 1-
bit units.
3. To read/write bits 8 to 15 of the PFCE9 register in 8-bit or 1-bit units, specify them as bits
0 to 7 of the PFCE9H register.
