PIN SYMBOL
DESCRIPTION
34
P5.0 (AI.0) Port 5 / AI.7–0: – I/O / A/D inputs. Port 5 provides eight lines which can be individually
33
P5.1 (AI.1) selected as open–drain psuedo–bi–directional I/O port pins or as A/D inputs. Pull–up
32
P5.2 (AI.2) resistors are required when using Port 5 as an I/O port.

P5.7 (AI.7)
26 P6.0 (PWO.0) Port 6 / PW0.3 – 0: – I/O / Pulse–Width Modulated Outputs. Port 6 provides eight lines
25 P6.1 (PWO.1) which can all serve as psuedo–bi–directional I/O port pins with internal pull–up
24 P6.2 (PWO.2) resistors. Six lines can be individually selected to serve the pulse–width modulator
23 P6.3 (PWO.3) function indicated below:

Port Function
Description
19 P6.7 / SOC P6.0 PWO.0
PWM 0 output (active high drive when enabled)
P6.1 PWO.1
PWM 1 output (active high drive when enabled)
P6.2 PWO.2
PWM 2 output (active high drive when enabled)
P6.3 PWO.3
PWM 3 output (active high drive when enabled)
P6.4 PWI.0
Optional clock input for PWM channels 0 and 2
P6.5 PWI.1
Optional clock input for PWM channels 1 and 3
P6.6 (none)
P6.7 SOC
External A / D start of conversion signal
69 P7.0 (AMI.0) Port 7 / AMI.7–0 / LED.7–0: – I/O / Activity Monitor Inputs / LED Control. Port 7 provides
(LED.0)
eight lines which can serve as a psuedo–bi–directional I/O port pins with internal pull–
70 P7.1 (AMI.1) ups or as Activity Monitor inputs. When used as Activity Monitor inputs, these pins are
(LED.1)
typically connected to the chip select line of an external peripheral device, and can be
71 P7.2 (AMI.2) programmed to sense active–high or active–low signals. Any pin which is programmed
(LED.2)
as an Activity Monitor input by setting its AMEn bit to a 1 will have its pull–up device dis-
72 P7.3 (AMI.3) abled and thereby function as an open–drain pin in order to eliminate unnecessary cur-
(LED.3)
rent drain. All port 7 pins are capable of controlling LED’s.

16 P8.0 (KSO.0) Port 8 / KSO.7–0:– I/O. Port 8 provides eight lines of open–drain psuedo–bi–directional
15 P8.1 (KSO.1) I/O port pins. Typically, these lines are used for key–scan outputs.
