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.

5.2.2 Freeze Controls (Freeze)

Default = 0

0 - Disabled

1 - Enabled

Function:

This function allows modifications to be made to the registers without the changes taking effect until the

FREEZE is disabled. To make multiple changes in the Control port registers take effect simultaneously, en-

able the FREEZE Bit, make all register changes, then Disable the FREEZE bit.
