Enabling External Programming Interface
NVM Programming
Figure 29-3. Memory map for PDI accessing the data and program memories.
NVM programming from the PDI requires enabling using the following steps:
When the NVMEN bit in the PDI STATUS register is set, the NVM interface is enabled and
active from the PDI.
When the PDI NVM interface is enabled, all memories in the device are memory mapped in the
PDI address space. The PDI controller does not need to access the NVM controller's address or
1. Load the RESET register in the PDI with 0x59.
2. Load the NVM key in the PDI.
3. Poll NVMEN in the PDI status register (PDI STATUS) until NVMEN is set.
