11.2.25 Channel 0 user configuration #3 register (CH0_CFG_U3)

The Channel 0 user configuration #3 register is a user programmable read/write register

which contains channel-specific configuration information. This register is included in the

read/write array error detection.

This register is readable and writable in DSI3 mode, SPI mode, I2C mode or PSI5

Programming Mode.
