I/O
Reference Input/Output. This pin is connected to the internal reference through a
series resistor and is the reference source for the analog-to-digital converter. The
nominal internal reference voltage is 2.5 V, which appears at the pin. See the Voltage
Reference Connections section on how to connect an external reference.

I
Input Port 1 (P1.4). Port 1 is an 8-bit input port only. Unlike other ports, Port 1 defaults
to analog input mode. To configure any Port 1 pin as a digital input, write a 0 to the
Port 1 bit. Port 1 pins are multifunctional and share the following functionality.
I
Single-Ended Analog Input (ADC4). Channel selection is via ADCCON2 SFR.
P1.5/ADC5/SS

I
Input Port 1 (P1.5). Port 1 is an 8-bit input port only. Unlike other ports, Port 1 defaults
to analog input mode. To configure any of these Port Pins as a digital input, write a 0
to the port bit. Port 1 pins are multifunction and share the following functionality.
I
Single-Ended Analog Input (ADC5). Channel selection is via ADCCON2 SFR.
I
Slave Select Input for the SPI Interface (SS).
