20.3.2 Block Diagram of H8SX/1654
Figure 20.4 shows the block structure of the 512-kbyte user MAT. The heavy-line frames indicate
the erase blocks. The thin-line frames indicate the programming units and the values inside the
frames stand for the addresses. The user MAT is divided into seven 64-kbyte blocks, one 32-kbyte
block, and eight 4-kbyte blocks. The user MAT can be erased in these divided block units.
Programming is done in 128-byte units starting from where the lower address is H'00 or H'80.
RAM emulation can be performed in the eight 4-kbyte blocks.
