bool nvm_config::manual_page_write

Manual write mode; if enabled, pages loaded into the NVM buffer will not be written until a separate write command is issued.

If disabled, writing to the last byte in the NVM page buffer will trigger an automatic write.

Note

If a partial page is to be written, a manual write command must be executed in either mode.
