10.0 Connection Memory Block Programming
This feature allows for fast initialization of the connection memory after power up.
10.1 Memory Block Programming Procedure
1. Set MBPE (bit 3) in the Control Register (CR) from low to high.
2. Configure BPD2 - 0 (bits 3 - 1) in the Internal Mode Selection (IMS) register to the desired values to be loaded
into CM_L.
3. Start the block programming by setting MBPS (bit 0) in the Internal Mode Selection Register (IMS) high. The val-
ues stored in BPD2 - 0 will be loaded into bits 2 - 0 of all CM_L positions. The remaining CM_L locations (bits 15
- 3) and the programmable values in the CM_H (bits 4 - 0) will be loaded with zero values.
The following tables show the resulting values that are in the CM_L and CM_H connection memory locations.
Note: Bits 15 to 5 are reserved in Connection Memory High and should always be 0.
It takes at least two frame periods (250
μ
s) to complete a block program cycle.
MBPS (bit 0) in the Control Register (CR) will automatically reset to a low position after the block programming
process has completed.
MBPE (bit 3) in the Internal Mode Selection (IMS) register must be cleared from high to low to terminate the block
programming process. This is not an automatic action taken by the device and must be performed manually.
Note: Once the block program has been initiated, it can be terminated at any time prior to completion by setting
MBPS (bit 0) in the Control Register (CR) or MBPE (bit 3) in the Internal Mode Selection (IMS) register to low. If the
MBPE bit was used to terminate the block programming, the MBPS bit will have to be set low before enabling other
device operations.
