LOCKBITS - Non-Volatile Memory Lock Bit Register
• Bit 0 - FLOAD: Flash Page Buffer Active Loading
The FLOAD flag indicates that the temporary Flash page buffer has been loaded with one or
more data bytes. Immediately after a Flash load command has been issues and byte is written to
NVMDR, the FLOAD flag is set, and it remains set until an Application- or Boot page write- or a
page buffer flush operation is executed.
S
This register is a direct mapping of the NVM Lockbits into the IO Memory Space, in order to
enable direct read access from the application software. Refer to
