Function
To read/write bits 8 to 15 of the PMDL register in 8-bit or 1-bit units, specify them
as bits 0 to 7 of the PMDLH register.
When the SMSEL bit of the EXIMC register = 1 (separate mode) and the BS30 to
BS00 bits of the BSC register = 0 (8-bit bus width), do not specify the AD8 to
AD15 pins.
To read/write bits 8 to 15 of the PMCDL register in 8-bit or 1-bit units, specify
them as bits 0 to 7 of the PMCDLH register.
The INTP7 pin and RXDA0 pin are alternate-function pins. When using the pin as
the RXDA0 pin, disable edge detection for the INTP7 alternate-function pin.
(Clear the INTF3.INTF31 bit and the INRT3.INTR31 bit to 0.) When using the pin
as the INTP7 pin, stop UARTA0 reception. (Clear the UA0CTL0.UA0RXE bit to
0.)
Between the P10 and P11 pins, when one pin is used as the I/O port, and the
other pin is used as the D/A output pin (ANO0, ANO1), make sure that the port
I/O level does not change during D/A output.
The INTP8 pin and RXDA3 pin are alternate-function pins. When using the pin as
the RXDA3 pin, disable edge detection for the INTP8 alternate-function pin.
(Clear the INTF8.INTF80 bit and the INTR8.INTR80 bit to 0.) When using the pin
as the INTP8 pin, stop UARTA3 reception. (Clear the UA0CTL3.UA3RXE bit to
0.)
When setting pins A0 to A15 as the alternate function, set the PMC9 register to
FFFFH for all 16 bits at once.
The RXDA1 and KR7 pins must not be used at the same time. When using the
RXDA1 pin, do not use the KR7 pin. When using the KR7 pin, do not use the
RXDA1 pin (it is recommended to set the PFC91 bit to 1 and clear the PFCE91 bit
to 0).
When setting pins A0 to A15 as the alternate function, set the PMC9 register to
FFFFH for all 16 bits at once.
To switch from the port mode to alternate-function mode in the following order.
<1> Set the PFn registerNote:
<2> Set the PFCn and PFCEn registers: Alternate-function selection
<3> Set the corresponding bit of the PMCn register to 1: Switch to alternate-
If the PMCn register is set first, note with caution that, at that moment or
depending on the change of the pin states in accordance with the setting of the
PFn, PFCn, and PFCEn registers, unexpected operations may occur.
Regardless of the port mode/alternate-function mode, the Pn register is read and
written as follows.
• Pn register read: Read the port output latch value (when PMn.PMnm bit = 0), or
• Pn register write: Write to the port output latch
The input signal to the alternate-function block is low level when the
PMCn.PMCnm bit is 0 due to the output of the PMCn register set value and the
pin level. Thus, depending on the port setting and alternatefunction operation
enable timing, unexpected operations may occur. Therefore, switch between the
mode and alternate-function mode in the following sequence.
• To switch from port mode to alternate-function mode (input)
• To switch from alternate-function mode (input) to port mode
read the pin states (PMn.PMnm bit = 1).
Set the pins to the alternate-function mode using the PMCn register and then
enable the alternatefunction operation.
Stop the alternate-function operation and then switch the pins to the port mode.
