Table 48.P1.1 Configuration (P11CR) [0x0E] [R/W]
Bit #
Field
Read/Write
Default
This register controls the operation of the P1.1 pin
The pull-up resistor on this pin is enabled by the P10CR Register
Note
There is no 2-mA sourcing capability on this pin. The pin can only sink 5 mA at V

Table 49.P1.2 Configuration (P12CR) [0x0F] [R/W]
Bit #
Field
Read/Write
Default
This register controls the operation of the P1.2
Bit 7
CLK Output
0 = The internally selected clock is not sent out onto P1.2 pin
1 = When CLK Output is set, the internally selected clock is sent out onto P1.2 pin.

Table 50.P1.3 Configuration (P13CR) [0x10] [R/W]
Bit #
Field
Read/Write
Default
This register controls the operation of the P1.3 pin
The P1.3 GPIO’s threshold is always set to TTL
When the SPI hardware is enabled, the output enable and output state of the pin is controlled by the SPI circuitry. When the SPI hardware is
disabled, the pin is controlled by the Output Enable bit and the corresponding bit in the P1 data register
Regardless of whether the pin is used as an SPI or GPIO pin the Int Enable, Int act Low, High Sink, Open Drain, and Pull-up Enable control the
behavior of the pin
50-mA sink drive capability is available
