nvm_prog_mode

nvm_remain<3:0>:

number of remaining write cycles permitted for NVM; the number is

decremented each time a write to the NVM is triggered

nvm_load:

´1´  trigger, or ‘0’  do not trigger an update of all configuration registers

from NVM; the nvm_rdy flag must be ‘1’ prior to triggering the update

nvm_rdy:

status of NVM controller: ´0´  NVM write / NVM update operation is in

progress, ´1´  NVM is ready to accept a new write or update trigger

nvm_prog_trig:

‘1’  trigger, or ‘0’ do not trigger an NVM write operation; the trigger is

only accepted if the NVM was unlocked before and nvm_remain<3:0> is

greater than ‘0’; flag nvm_rdy must be ‘1’ prior to triggering the write cycle

nvm_prog_mode: ‘1’  unlock, or ‘0’  lock NVM write operation
