3.3 Operating Mode Descriptions
3.3.1 Mode 1 (H8S/2319C F-ZTAT Only)
This is a flash memory boot mode. See section 17, ROM, for details.
Except for the fact that flash memory programming and erasing can be performed, operation in
this mode is the same as in advanced single-chip mode.
3.3.2 Mode 2 (H8S/2319 F-ZTAT and H8S/2319C F-ZTAT Only)
This is a flash memory boot mode. See section 17, ROM, for details.
Except for the fact that flash memory programming and erasing can be performed, operation in
this mode is the same as in advanced expanded mode with on-chip ROM enabled.
