Chapter 2 Description of Pins
2
2.13 P12_0, P12_1: Input/Output Pins
2-bit I/O pins of Port 12. Individual bits can be specified as input or output by the Port
12 mode register (P12IO).
P12_0 can also be made to function (secondary function) as an output pin for internal
operation by setting the
EA
pin to a "L" level. In the ML66592, P12_1, also, functions as
its secondary function.
<Description of Secondary Functions of Each Pin>
• A16 (P12_0)
If the
EA
pin has been set to a "L" level, this pin functions to output address A16 that
is used to access external expanded program memory.
• A17 (P12_1)
If the
EA
pin has been set to a "L" level, this pin functions to output address A17 that
is used to access external expanded program memory. (ML66592 only)
2.14 AI0–AI23: Input Pins
Analog input pins of the A/D converter.
2.15 AV
DD
: Input Pin
Power input pin of the A/D converter. Supply the same voltage as V
DD
to this pin.
2.16 V
REF
: Input Pin
Reference voltage input pin of the A/D converter.
2.17 AGND: Input Pin
GND pin of the A/D converter.
2.18 OSC0, OSC1: Input Pin, Output Pin
Connection pins to connect the crystal oscillator, ceramic resonator or capacitors for
basic clock oscillation. If the basic clock is supplied externally, input to the OSC0 pin,
and leave the OSC1 pin open.
2.19
OE
: Input Pin
When the
OE
pin is in "H" level, and when each of P0–P2, P3_0–P3_3, P7_4–P7_7,
P8, P10_0–P10_4, P12_0, and P12_1 is in output status, each pin goes into high
impedance state.
2.20 NMI: Input Pin
Input pin of a non-maskable interrupt request.
2.21
RES
: Input Pin
Input pin of low active reset.
