Revision ID (REV) [Read Only]
000 - Revision A0
001 - Revision B0
Function:
This read-only register can be used to identify the model and revision number of the device.
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.
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,
enable the FREEZE Bit, make all register changes, then Disable the FREEZE bit.
