Section 17 Flash Memory

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.
