REG[4:0]

BIT[2:0]

Default

Bits 7 to 3: Status Register (REG[4:0]). When GPIOCR1.GPIO0C=01xx, this field specifies the register of the

status bit that GPIO0 will follow while the BIT field below specifies the status bit within the register. Setting the

combination of this f

ield and the BIT field below to point to a bit that isn’t implemented as a real-time or latched status

Bits 2 to 0: Status Bit (BIT[2:0]). When GPIOCR1.GPIO0C=01xx, the REG field above specifies the register of the

status bit that GPIO0 will follow while this field specifies the status bit within the register. Setting the combination of

the RE

G field and this field to point to a bit that isn’t implemented as a real-time or latched status register bit results

in GPIO1 being driven low. 000=bit 0 of the register. 111=bit 7 of the register.

Note: The device does not allow the GPIO status register bits in GPIOSR to be followed by a GPIO.
