SFR Definition 6.1. AMX0SL: AMUX Channel Select
Bits 7–6:
UNUSED. Read = 00b; Write = don’t care
Bit 5:
AMXEN enable
0: AMXEN disabled and port pins are unavailable for analog use.
1: AMXEN enabled to use/select port pins for analog use.
Bits 4–3:
PRTSL1–0: Port Select Bits*.
00: Port0 select to configure pin for analog input from this port.
01: Port1 select to configure pin for analog input from this port.
10: Port2 select to configure pin for analog input from this port.
11: Port3 select to configure pin for analog input from this port.
Bits 2–0:PINSL2–0: Pin Select Bits
000: Pin 0 of selected port (above) to be used for analog input.
001: Pin 1 of selected port (above) to be used for analog input.
010: Pin 2 of selected port (above) to be used for analog input.
011: Pin 3 of selected port (above) to be used for analog input.
100: Pin 4 of selected port (above) to be used for analog input.
101: Pin 5 of selected port (above) to be used for analog input.
110: Pin 6 of selected port (above) to be used for analog input.
111: Pin 7 of selected port (above) to be used for analog input.
* Selecting a port for analog input does NOT default all pins of that port as analog input. After select-
ing a port for analog input, a pin must be selected using pin select bits (PINSL2–0). For example,
after setting the AMXEN to ‘1’, setting PRTSL1–0 to “11”, and setting PINSL2–0 to “100” P3.4 is
configured as analog input. All other Port 3 pins remain as GPIO pins. Also note that in order to use
a port pin as analog input, its input mode should be set to analog. Please see section 14.2.
