If accessing to DRAM area, these pins output row address and
column address separated in time by multiplexing.
This is an 8-bit I/O port equivalent to P0.
These pins output 8 high-order address bits (A
address bit (A
These pins output CS
signals used to specify an access space.
When accessing to DRAM area while DW signal is “L”, write to DRAM.
CASL and CASH show timing when latching to line address. When
CASL accesses to even address, and CASH to odd, these two pins
become “L”. RAS signal shows timing when latching to row address.
This is an 8-bit I/O port equivalent to P0. When set for input in single
chip mode, microprocessor mode and memory expansion mode the
user can specify in units of four bits via software whether or not they
are tied to a pull-up resistance. Pins in this port also function as
UART0 and UART1 I/O pins as selected by software.
This is an 8-bit I/O port equivalent to P6 (P7
open drain output). Pins in this port also function as timer A
timer B5 or UART2 I/O pins as selected by software.
This is an 8-bit I/O port equivalent to P0. P5

Output WRL, WRH (WR and BHE), RD, BCLK, HLDA, and ALE
signals. WRL and WRH, and BHE and WR can be switched using
software control.
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”.
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.
While the input level at the HOLD pin is “L”, the microcomputer is
placed in the hold state. While in the hold state, HLDA outputs an “L”
level. ALE is used to latch the address. While the input level of the
RDY pin is “L”, the bus of microcomputer is in the wait state.
P8
Using software, they can be made to function as the I/O pins for timer
A4 and the input pins for external interrupts. P8
using software to function as the I/O pins for a sub clock generation
circuit. In this case, connect a quartz oscillator between P8
pin) and P8
for NMI. The NMI interrupt is generated when the input at this pin
changes from “H” to “L”. The NMI function cannot be canceled using
software. The pull-up cannot be set for this pin.
This is an 8-bit I/O port equivalent to P6. Pins in this port also
function as UART3 and UART4 I/O pins, Timer B0–B4 input pins, D/A
converter output pins, A/D converter extended input pins, or A/D
trigger input pins as selected by software.
This is an 8-bit I/O port equivalent to P6. Pins in this port also
function as A/D converter input pins. Furthermore, P10
function as input pins for the key input interrupt function.
