Description
Jump Address, high byte
The most significant byte of the address at which the C868 would jump
to after the downloading process. This byte indicates whether to jump to
XRAM or SRAM and the respective software unlock sequence and chip
mode conversion should be invoked before jumping. Note that only the
Jump Address of the last transfer block is effective.
Jump Address, low byte
The least significant byte of the address at which the C868 would jump
to after the downloading process. Note that only the Jump Address of
the last transfer block is effective.
Checksum
This byte is the checksum of the previous 7 bytes of the header block. It
is obtained by XORING the previous 7 bytes.
Data
Data to be written to the XRAM/SRAM. The header will not be written to
XRAM/SRAM.
