General Purpose I/O (GPIO)
7.3.2.1.13 GPS GPIO Simple Interrupt Interrupt Enable Register —MBAR + 0x0B30
Bit Name Description
0:7 SIDVO Individual bits to control the state of pins configured as GPIO output.
bit 0 controls GPIO_SINT_7 (ETH_16 pin)
bit 1 controls GPIO_SINT_6 (ETH_15 pin)
bit 2 controls GPIO_SINT_5 (ETH_14 pin)
bit 3 controls GPIO_SINT_4 (ETH_13 pin)
bit 4 controls GPIO_SINT_3 (USB1_9 pin)
bit 5 controls GPIO_SINT_2 (PSC3_8 pin)
bit 6 controls GPIO_SINT_1 (PSC3_5 pin)
bit 7 controls GPIO_SINT_0 (PSC3_4 pin)
0 = Drive 0 on the pin (default)
1 = Drive 1 on the pin

Bit Name Description
0:7 SIINTEN Individual bits to enable Interrupt generation for each GPIO pin configured as an Input.
bit 0 controls GPIO_SINT_7 (ETH_16 pin)
bit 1 controls GPIO_SINT_6 (ETH_15 pin)
bit 2 controls GPIO_SINT_5 (ETH_14 pin)
bit 3 controls GPIO_SINT_4 (ETH_13 pin)
bit 4 controls GPIO_SINT_3 (USB1_9 pin)
bit 5 controls GPIO_SINT_2 (PSC3_8 pin)
bit 6 controls GPIO_SINT_1 (PSC3_5 pin)
bit 7 controls GPIO_SINT_0 (PSC3_4 pin)
0 = Pin cannot generate an Interrupt (default)
1 = Pin can generate an Interrupt if configured as an Input GPIO

Note: See Interrupt Type data in GPS GPIO Simple Interrupt Interrupt Types Register —MBAR + 0x0B34 Register. Also,
the Master Interrupt Enable bit must be set in the GPS GPIO Simple Interrupt Master Enable Register —MBAR + 0x0B38
Register, before any Simple Interrupt pin can generate an Interrupt.
