1.4.19
PAD[15:0] are the analog inputs for the analog to digital converter (ADC). They can also be configured as
general purpose digital input or output pin. When enabled as digital inputs or outputs, the PAD[15:0] can
also be configured as Keypad Wake-up pins (KWU) and generate interrupts causing the MCU to exit
STOP or WAIT mode. Consult
“Analog-to-Digital Converter (ATD10B16CV4)”
1.4.20
PM7 is a general purpose input or output pin. When the IIC module is enabled it becomes the serial clock
line (SCL) for the IIC module (IIC). While in reset and immediately out of reset the PM7 pin is configured
as a high impedance input pin. Consult
Chapter 10, “Inter-Integrated Circuit (IICV2)”
1.4.21
PM6 is a general purpose input or output pin. When the IIC module is enabled it becomes the Serial Data
Line (SDL) for the IIC module (IIC). While in reset and immediately out of reset the PM6 pin is configured
as a high impedance input pin. Consult
Chapter 10, “Inter-Integrated Circuit (IICV2)”
1.4.22
PM5 is a general purpose input or output. When the Serial Communications Interface 2 (SCI2) transmitter
is enabled the PM5 pin is configured as the transmit pin TXD2 of SCI2. While in reset and immediately
out of reset the PM5 pin is configured as a high impedance input pin. Consult

about pin configurations.
1.4.23
PM4 is a general purpose input or output. When the Serial Communications Interface 2 (SCI2) receiver is
enabled the PM4 pin is configured as the receive pin RXD2 of SCI2. While in reset and immediately out
of reset the PM4 pin is configured as a high impedance input pin. Consult

about pin configurations.
1.4.24
PM3 is a general purpose input or output pin. While in reset and immediately out of reset the PM3 pin is
configured as a high impedance input pin. Consult
for information about pin configurations.
