Data is written when WR is "L". Data is read when RD is "L". Odd addresses are
accessed when BHE is "L". Use this mode when using an 8-bit external data bus.

This is an 8-bit CMOS I/O port. The input/output port direction register allows
each pin to be set individually. When used for input, the port can be set to
include internal pull-up resistors in 4-pin blocks.
These pins input and output 8 low-order data bits when set as a separate bus.
Data pins for communicating with AND type flash memory devices
This is an 8-bit I/O port equivalent to P0.
These pins input and output 8 high-order data bits when set as a separate bus.
Control signal pins for communicating with AND type flash memory devices
This is an 8-bit I/O port equivalent to P0.
These pins output 8 low-order address bits.
This is an 8-bit I/O port equivalent to P0.
These pins output 8 middle-order address bits.
This is an 8-bit I/O port equivalent to P0.
These pins output 4 high-order address bits.
P4
This is an 8-bit I/O port equivalent to P0.
Ouput WRL, WRH (WR, BHE), and RD bus control signals. Using WRL and
WRH or WR and BHE can be switched using software control.
Output operation clock for the CPU.
The HLDA pin output is "L" while the MCU is in the hold state.
The ALE pin can be used to latch the address.
With a 16-bit external data bus, data is written to even addresses when the
WRL signal is "L", and to the odd addresses when the WRH signal is "L". Data
is read when RD is "L".
While the HOLD pin input is "L", the MCU is placed in the Hold state.
While the RDY pin input is "L", the MCU is in the ready state.
