5.2.1
Control Port Enable (CPEN)
Default = 0
0 - Disabled
1 - Enabled
Function:
This bit defaults to 0, allowing the device to power-up in Stand-Alone mode. The Control port mode can
be accessed by setting this bit to 1. This will allow the operation of the device to be controlled by the reg-
isters and the pin definitions will conform to Control Port Mode. To accomplish a clean power-up, the user
should write this bit within 10 ms following the release of Reset.
