BUSY
To program or write to the UFM, you must first perform a sequence to load the
reference address into the address register. DRSHFT must then be asserted high to load
the data serially into the data register starting with the MSB. Loading an address into
the address register and loading data into the data register can be done concurrently.
After the 16 bits of data have been successfully shifted into the data register, the
PROGRAM signal must be asserted high to start writing to the UFM. On the rising edge,
the data currently in the data register is written to the location currently in the address
register. The BUSY signal is asserted until the program sequence is completed. The data
and address register should not be modified until the BUSY signal is de-asserted, or the
flash content will be corrupted. The PROGRAM signal is ignored if the BUSY signal is
asserted. When the PROGRAM signal is applied at exactly the same time as the ERASE
signal, the behavior is undefined and the flash content is corrupted.
