The specified address should be on a boundary corresponding to the unit of programming
(programming size). For example, when programming 128 bytes of data, the lowest byte of the
address should be either H'00 or H'80. When less than 128 bytes of data are to be programmed, the
host should transmit the data after padding the vacant bytes with H'FF.
To terminate programming of a given MAT, send a 128-byte programming command with the
address field H'FFFFFFFF. This informs the boot program that all data for the selected MAT have
been sent; the boot program then waits for the next programming/erasure selection command.
