Revision 1.07

Edge Detection Register (WKEDG2)

Byte-wide read/write register that configures the trigger condition of the input signals WUI20 to WUI27. The functionality of

the register is identical to the WKEDG1 register described above.

Location: 00 FFC216

Type: R/W

Edge Detection Register (WKEDG3)

Byte-wide read/write register that configures the trigger condition of the input signals WUI30 to WUI37. The functionality of

the register is identical to the WKEDG1 register described above.

Location: 00 FFC416

Type: R/W

Edge Detection Register (WKEDG4)

Byte-wide read/write register that configures the trigger condition of the input signals WUI40 to WUI47. The functionality of

the register is identical to the WKEDG1 register described above.

Location: 00 FFC616

Type: R/W

Pending Register (WKPND1)

Byte-wide read/write register that latches the occurrence of a selected trigger condition associated with the input signals

WUI10 to WUI17. On reset, the WKPND1 register is cleared (0). This indicates that no occurrence of the selected trigger

condition is pending.

Note: Only software can set the register bits; only the WKPCL1 register can clear them. Writing a 0 to any of the bits leaves

their values unchanged. The WKPND1 register format is shown below:

Location: 00 FFC816

Type: R/W

Pending Register (WKPND2)

Byte-wide read/write register that latches the occurrence of a selected trigger condition associated with the input signals

WUI20 to WUI27. For a detailed description of the register see the above description of the WKPND1 register.

Location: 00 FFCC16

Type: R/W

Pending Register (WKPND3)

Byte-wide read/write register that latches the occurrence of a selected trigger condition associated with the input signals

WUI30 to WUI37. For a detailed description of the register see the above description of the WKPND1 register.

Location: 00 FFD016

Type: R/W
