Each pin declared as DIO can be configured independently as an input or output with the bits of the DIO_DIRn registers. Table
51 lists the direction registers and configurability associated with each group of DIO pins. Table 52 shows the configuration for
a DIO pin through its associated bit in its DIO_DIR register.
DIO_DIR bit

DIO Pin Function

Table 52: DIO_DIR Control Bit
Values read from and written into the DIO ports use the data registers P0, P1 and P2.
A 3-bit configuration word, I/O RAM register, DIO_Rx (0x2009[2:0] through 0x200E[6:4]) can be used for certain pins, when
configured as DIO, to individually assign an internal resource such as an interrupt or a timer control (see Table 51 for DIO pins
available for this option). This way, DIO pins can be tracked even if they are configured as outputs. This feature is useful for
pulse counting. The control resources selectable for the DIO pins are listed in Table 53. If more than one input is connected to
the same resource, the resources are combined using a logical OR.
DIO_R
Value
Resource Selected for DIO Pin
0
NONE
1
Reserved
2
T0 (counter0 clock)
3
T1 (counter1 clock)
4
High priority I/O interrupt (INT0 rising)
5
Low priority I/O interrupt (INT1 rising)
6
High priority I/O interrupt (INT0 falling)
7
Low priority I/O interrupt (INT1 falling)
Table 53: Selectable Controls using the DIO_DIR Bits
Additionally, if DIO6 and DIO7 are declared outputs, they can be configured as dedicated pulse outputs (WPULSE = DIO6,
VARPULSE = DIO7) using the I/O RAM registers DIO_PW (0x2008[2]) and DIO_PV (0x2008[3]). In this case, DIO6 and DIO7
are under CE control. DIO4 and DIO5 can be configured to implement the EEPROM Interface by setting the I/O RAM register
DIO_EEX (0x2008[4]).
