occurred. Write 1 to clear this bit. Writing 0 is invalid.
5
STS_GP25EDGE R/W VSB3V Indicate GPIO25 Edge Status. If set to 1, the edge of GPIO25 has
occurred. Write 1 to clear this bit. Writing 0 is invalid.
4
STS_GP24EDGE R/W VSB3V Indicate GPIO24 Edge Status. If set to 1, the edge of GPIO24 has
occurred. Write 1 to clear this bit. Writing 0 is invalid.
3
STS_GP23EDGE R/W VSB3V Indicate GPIO23 Edge Status. If set to 1, the edge of GPIO23 has
occurred. Write 1 to clear this bit. Writing 0 is invalid.
2
STS_GP22EDGE R/W VSB3V Indicate GPIO22 Edge Status. If set to 1, the edge of GPIO22 has
occurred. Write 1 to clear this bit. Writing 0 is invalid.
1
STS_GP21EDGE R/W VSB3V Indicate GPIO11 Edge Status. If set to 1, the edge of GPIO21 has
occurred. Write 1 to clear this bit. Writing 0 is invalid.
