7.6.4.1
A target STP is the set of transmission parameters that describes the requested link. The
following registers enable access to target STP parameters:
•
•
•
To change a parameter in a target STP, do the following:
1. Write the opcode of the parameter to the VOC_OC
2. Write the new value of the parameter to the VOC_DAT
3. Write 40
4. Read VOC_OC to verify that the operation:

To copy an entire STP from RAM into EEPROM for use as a new default STP and write
valid signatures to the appropriate addresses in the EEPROM, see
