also be configured as Keypad Wake-up pins (KWU) and generate interrupts causing the MCU to exit STOP
or WAIT mode. Consult the Port Integration Module (PIM) PIM_9E128 block description chapter and the
ATD_10B16C block description chapter for information about pin configurations.
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 the Port Integration Module (PIM) PIM_9E128 block description
chapter and the IIC block description chapter for information about pin configurations.
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 the Port Integration Module (PIM) PIM_9E128 block description
chapter and the IIC block description chapter for information about pin configurations.
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 the Port Integration Module
(PIM) PIM_9E128 block description chapter and the SCI block description chapter for information 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 the Port Integration Module
(PIM) PIM_9E128 block description chapter and the SCI block description chapter for information 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 the Port Integration Module (PIM) PIM_9E128 block
description chapter for information about pin configurations.
1.4.25
PM1 is a general purpose input or output pin. When the Digital to Analog module 1 (DAC1) is enabled the
PM1 pin is configured as the analog output DA01 of DAC1. While in reset and immediately out of reset
the PM1 pin is configured as a high impedance input pin. Consult the Port Integration Module (PIM)
