E
(CMOS/H)
General-purpose I/O port
This function is always valid.
TIN0, TIN1
Event input pins of 16-bit reload timer 0 and 1
Because this input is used as required when the
16-bit reload timer is performing input operations,
and it is necessary to stop outputs by other func-
tions unless such outputs are made intentionally.

E
(CMOS/H)
General-purpose I/O port
This function is valid when outputs from 16-bit re-
load timer 0 and 1 are disabled.
TOT0,
TOT1
Output pins for 16-bit reload timer 0 and 1
This function is valid when output from 16-bit re-
load timer 0 and 1 are enabled.

General-purpose I/O port
This function is valid in the single-chip mode.
ALE
Address latch enable output pin
This function is valid in the mode where the exter-
nal bus is valid.

General-purpose I/O port
This function is valid in the single-chip mode.
RD
Read strobe output pin for the data bus
This function is valid in the mode where the exter-
nal bus is valid.

B
(CMOS)
General-purpose I/O port
This function is valid in the single-chip mode or
WRL/WR pin output is disabled.
WRL
Write strobe output pin for the data bus
This function is valid when WRL/WR pin output is
enabled in the mode where external bus is valid.
WRL is used for holding the lower 8-bit for write
strobe in 16-bit access operations, while WR is
used for holding 8-bit data for write strobe in
8-bit access operations.

B
(CMOS)
General-purpose I/O port
This function is valid in the single-chip mode, in the
external bus 8-bit mode, or WRH pin output is dis-
abled.
WRH
Write strobe output pin for the upper 8-bit of the
data bus
This function is valid when the external bus 16-bit
mode is selected in the mode where the external
bus is valid, and WRH output pin is enabled.
