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 registers 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.
