Address* Name
H'EE004 Port 5 data direction register
H'FFFD4 Port 5 data register
H'EE03F Port 5 input pull-up control register
Note: * Lower 20 bits of the address in advanced mode.
Port 5 Data Direction Register (P5DDR): P5DDR is an 8-bit write-only register that can select
input or output for each pin in port 5.
Bits 7 to 4 are reserved. They are fixed at 1, and cannot be modified.
Modes 1 to 4 (Expanded Modes with On-Chip ROM Disabled): P5DDR values are fixed at 1.
Port 5 functions as an address bus.
Modes 5 (Expanded Modes with On-Chip ROM Enabled): Following a reset, port 5 is an input
port. A pin in port 5 becomes an address output pin if the corresponding P5DDR bit is set to 1, and
an input port if this bit is cleared to 0.
Mode 6 and 7 (Single-Chip Mode): Port 5 functions as an input/output port. A pin in port 5
becomes an output port if the corresponding P5DDR bit is set to 1, and an input port if this bit is
cleared to 0.
In modes 1 to 4, P5DDR bits are always read as 1, and cannot be modified.
