(STBC)
General-purpose I/O ports
Pull-up resistors can be set (RD07 to RD00 = “1”) using the
pull-up resistor setting register (RDR0).
The setting does not apply for ports set as outputs (D07 to D00
= “1”: invalid at the output setting).
AD00 to AD07
In external bus mode, the pins function as the lower data I/O or
lower address outputs (AD00 to AD07).
91 to 98
93 to 100 P10 to P17
E
(STBC)
General-purpose I/O ports
Pull-up resistors can be set (RD17 to RD10 = “1”) using the
pull-up resistor setting register (RDR1).
The setting does not apply for ports set as outputs (D17 to D10
= “1”: invalid at the output setting).
AD08 to AD15
In 16-bit external bus mode, the pins function as the upper data
I/O or middle address outputs (AD08 to AD15).
