CHAPTER 13 GENERAL PURPOSE I/O UNIT (GIU)
These bits define the type of interrupt generated when the GPIO11 pin is defined
as a general-purpose input:
00 : Negative edge triggered interrupt
01 : Positive edge triggered interrupt
10 : Low level triggered interrupt
11 : High level triggered interrupt
These bits define the type of interrupt generated when the GPIO10 pin is defined
as a general-purpose input:
00 : Negative edge triggered interrupt
01 : Positive edge triggered interrupt
10 : Low level triggered interrupt
11 : High level triggered interrupt
These bits define the type of interrupt generated when the GPIO9 pin is defined as
a general-purpose input:
00 : Negative edge triggered interrupt
01 : Positive edge triggered interrupt
10 : Low level triggered interrupt
11 : High level triggered interrupt
These bits define the type of interrupt generated when the GPIO8 pin is defined as
a general-purpose input:
00 : Negative edge triggered interrupt
01 : Positive edge triggered interrupt
10 : Low level triggered interrupt
