Bit 7: GPIO Port 1 Interrupt Enable 0 = Mask GPIO Port 1 interrupt

1 = Unmask GPIO Port 1 interrupt Bit 6: Sleep Timer Interrupt Enable 0 = Mask Sleep Timer interrupt

1 = Unmask Sleep Timer interrupt Bit 5: INT1 Interrupt Enable

0 = Mask INT1 interrupt

1 = Unmask INT1 interrupt

Bit 4: GPIO Port 0 Interrupt Enable 0 = Mask GPIO Port 0 interrupt

1 = Unmask GPIO Port 0 interrupt Bit 3: SPI Receive Interrupt Enable 0 = Mask SPI Receive interrupt

1 = Unmask SPI Receive interrupt Bit 2: SPI Transmit Interrupt Enable 0 = Mask SPI Transmit interrupt

1 = Unmask SPI Transmit interrupt Bit 1: INT0 Interrupt Enable

0 = Mask INT0 interrupt

1 = Unmask INT0 interrupt

Bit 0: POR/LVD Interrupt Enable 0 = Mask POR/LVD interrupt

1 = Unmask POR/LVD interrupt

Table 17-9. Interrupt Vector Clear Register (INT_VC) [0xE2] [R/W]

Bit #	7	6	5	4	3	2	1	0
Field				Pending Interrupt [7:0]
Read/Write	R/W	R/W	R/W	R/W	R/W	R/W	R/W	R/W
Default	0	0	0	0	0	0	0	0

The Interrupt Vector Clear Register (INT_VC) holds the interrupt vector for the highest priority pending interrupt when read, and when written clears all pending interrupts.

Bit [7:0]: Pending Interrupt [7:0]

8-bit data value holds the interrupt vector for the highest priority pending interrupt. Writing to this register clears all pending interrupts.
