Table 21.12 Programming/Erasing Commands - Renesas H8S Series Hardware Manual

7. After selection of the device and clock mode, programming/erasing information of the user
boot MAT and user MAT should be inquired using the user boot MAT information inquiry
(H'24), user MAT information inquiry (H'25), erased block information inquiry (H'26), and
programming unit inquiry (H'27).
8. After making inquiries and selecting a new bit rate, issue the transition to
programming/erasing state command (H'40). The boot program will then enter the
programming/erasing state.
(9) Programming/Erasing State
In the programming/erasing state, a programming selection command makes the boot program
select the programming method, a 128-byte programming command makes it program the
memory with data, and an erasing selection command and block erasing command make it erase
the block. The programming/erasing commands are listed in table 21.12.
