54
P50
E
General-purpose I/O port
This port is available in the single-chip mode and when the CLK
output is disabled.
CLK
CLK output pin
This pin is available in an external-bus mode with the CLK output
enabled.
55
P51
E
General-purpose I/O port
This port is available in the single-chip mode or when the ready
function is disable.
RDY
Ready signal input pin
This pin is available in an external-bus mode and when the ready
function is enabled.
56
P52
E
General-purpose I/O port
This port is available in the single-chip mode or when the hold
function is disabled.
HAK
Hold acknowledge output pin
This pin is available in an external-bus mode and when the hold
function is enabled.
57
P53
E
General-purpose I/O port
This port is available in the single-chip mode or when the hold
function is disabled in an external-bus mode.
HRQ
Hold request input pin
This pin is available in an external-bus mode and when the hold
function is enabled.
Since this input is used during this operation at any time, the
output by any other function must be suspended unless the
output is intentionally performed.
58
P54
D
General-purpose I/O port
This port is available in the single-chip mode, in the external bus
8-bit mode, or when the WRH pin output is disabled.
When these pins are open in input mode, through current may
leak in stop mode/reset mode, be sure to fix these pins to VCC/VSS
level to use these pins in input mode.
CTS0
UART (ch.0) clear-to-send input pin
Since this input is used whenever the UART (ch.0) CTS function
is enabled, the output by any other function must be suspended
unless the output is intentionally performed.
When these pins are open in input mode, through current may
leak in stop mode/reset mode, be sure to fix these pins to VCC/VSS
level to use these pins in input mode.
WRH
Write strobe output pin for the upper eight bits of data bus
This pin is available in the external bus 16-bit mode with the
WRH pin output enabled in an external-bus mode.
