NVMCSR - Non-Volatile Memory Control and Status Register
• Bits 5:0 – NVMCMD[5:0]: Non-Volatile Memory Command
These bits define the programming commands for the flash, as shown in
Table 19-9.
• Bit 7 – NVMBSY: Non-Volatile Memory Busy
This bit indicates the NVM memory (Flash memory and Lock Bits) is busy, being programmed.
This bit is set when a program operation is started, and it remains set until the operation has
been completed.
• Bits 6:0 – Res: Reserved Bits
These bits are reserved and will always read as zero.
