Interrupt Status Register

17.1.1 Rising Edge Pending Register n (WKRPNDn)

The WKRPNDn registers are 32-bit, read/write registers that indicate whether a rising edge has been

detected on the corresponding MIWU input. Bits 31:0 of WKRPND1 correspond to MIWU inputs 31:0 Bits

31:0 of WKRPND2 correspond to MIWU inputs 63:32. Writing 1 to bits in the WKCLRn registers clears the

corresponding bits in the WKRPNDn registers. The WKRPNDn registers are cleared at reset. The register

format is shown below.

WKRPD

The Wake-Up Rising Edge Pending bits indicate whether a rising edge has occurred on the

corresponding MIWU inputs since the bits were last cleared.

0 – No rising edge occurred.

1 – Rising edge occurred.

17.1.2 Falling Edge Pending Register n (WKFPNDn)

The WKFPNDn registers are 32-bit, read/write registers that indicate whether a falling edge has been

detected on the corresponding MIWU input. Bits 31:0 of WKFPND1 correspond to MIWU inputs 31:0 Bits

31:0 of WKFPND2 correspond to MIWU inputs 63:32. Writing 1 to bits in the WKCLRn registers clears the

corresponding bits in the WKFPNDn registers. The WKFPNDn registers are cleared at reset. The register

format is shown below.

WKFPD

WKFPD The Wake-Up Falling Edge Pending bits indicate whether a falling edge has occurred on the

corresponding MIWU inputs since the bits were last cleared.

0 – No falling edge occurred.

1 – Falling edge occurred.

17.1.3 Clear Pending Register n (WKCLRn)

The WKCLRn registers are 32-bit, write-only registers that clear bits in the WKRPNDn and WKFPNDn

registers. Writing 1 to a WKCLRn bit clears the corresponding bit in each of the other registers. WKCLR1

clears bits in WKRPND1 and WKFPND1, and WKCLR2 clears bits in WKRPND2 and WKFPND2. The
