GPIO Clear Register
The GPIO Clear Register can directly deassert a corresponding line in the Data Register without
requiring a read-modify-write cycle.

GPIO15_CLEAR
-
GPIO15 Clear bit— asserts the GPIO15 line. Polarity of “clear” is
determined by the CPIO Control Register settings.
0 = does not affect the corresponding GPIO15 bit
1 = clear the corresponding GPIO15 bit
14
GPIO14_CLEAR
-
GPIO14 Clear bit— asserts the GPIO14 line. Polarity of “clear” is
determined by the CPIO Control Register settings.
0 = does not affect the corresponding GPIO14 bit
1 = clear the corresponding GPIO14 bit
13
GPIO13_CLEAR
-
GPIO13 Clear bit— asserts the GPIO13 line. Polarity of “clear” is
decremented by the CPIO Control Register settings.
0 = does not affect the corresponding GPIO13 bit
1 = clear the corresponding GPIO13 bit
12
GPIO12_CLEAR
-
GPIO12 Clear bit— asserts the GPIO12 line. Polarity of “clear” is
decremented by the CPIO Control Register settings.
0 = does not affect the corresponding GPIO12 bit
1 = clear the corresponding GPIO12 bit
11
GPIO11_CLEAR
-
GPIO11 Clear bit— asserts the GPIO11 line. Polarity of “clear” is
determined by the CPIO Control Register settings.
0 = does not affect the corresponding GPIO11 bit
1 = clear the corresponding GPIO11 bit
