trol parameters stored in Non-Volatile Memory (NVM). Refer to
Table 1 .
• DC132 NVM Initialize
The NVM Initialize routine provides the capability to initialize (set to default) machine con-
trol parameters stored in Non-Volatile Memory (NVM). Refer to
Table 1
• DC330 Test Routines
This routine provides the capability to verify component functionality by monitoring input
signals and controlling output states. Refer to
Table 2 .
