This field is used to define the direction of the channel 1
(input or output), and the selection of input pin when
C3
EN=’0’:
00: Output
01: Input, C3IN is mapped on C3IRAW
10: Input, C3IN is mapped on C4IRAW
11: Input, C3IN is mapped on STCI. This mode works only
when the internal trigger input is selected by STIS.

When the channel 1 is configured as output mode:
0: C1OUT is active high
1: C1OUT is active low
When the channel 1 is configured as input mode:
0: C1IN active edge is on its rising edge. When used as
external trigger, C1IN is not inverted.
1: C1IN active edge is on its falling edge. When used as
external trigger, C1IN is inverted.

Channel 1 enable
0: Input or output is disabled
1: Input or output is enabled

CxOUT = polarity, Cx_EN=1
Note: The state of the external I/O pins connected to the standard CxOUT channel depends on the
CxOUT channel state and the GPIO and IOMUX registers.
