This register controls the operation of the P1.0 (D+) pin when the USB interface is not enabled, allowing the pin to be used as a PS2 interface or a GPIO. See Table 21-1on page 58 for information on enabling the USB. When the USB is enabled, none of the controls in this register have any affect on the P1.0 pin.

Note The P1.0 is an open drain only output. It can actively drive a signal low, but cannot actively drive a signal high.

Bit 1: PS/2 Pull up Enable

0 = Disable the 5K ohm pull up resistors

1 = Enable 5K ohm pull up resistors for both P1.0 and P1.1. Enable the use of the P1.0 (D+) and P1.1 (D–) pins as a PS2 style interface.

This register controls the operation of the P1.1 (D–) pin when the USB interface is not enabled, allowing the pin to be used as a PS2 interface or a GPIO. See Table 21-1on page 58 for information on enabling USB. When USB is enabled, none of the controls in this register have any affect on the P1.1 pin. When USB is disabled, the 5K ohm pull up resistor on this pin may be enabled by the PS/2 Pull Up Enable bit of the P10CR Register (Table 14-10)

Note There is no 2 mA sourcing capability on this pin. The pin can only sink 5 mA at VOL3 (See section DC Characteristics on page 68)

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

Note:Table 10-7, “Clock IO Config (CLKIOCR) [0x32] [R/W],” on page 26 is used to select the external or internal clock in enCoRe II devices
