Item Host Operation Operation of this LSI
Transfer of programming
control program and sum
value
Transmits programming control
program in N-byte divisions.
Transfers received data to on-
chip RAM
Transmits sum value (two's
complement of sum total of
programming control program
(1 byte))
Calculates sum total of
received sum value and 1 byte
units of programming control
program transferred to on-chip
RAM
If sum is 0, transmits H'AA to
host
If sum is not 0, transmits H'FF
to host halts operation
Memory erase Starts total erase of flash
memory
Transmits total erase status
command (H'3A)
Transmits H'11 to host if total
erase processing is being
executed when total erase
status command is received
Transmits H'06 to host if total
erase of all blocks has been
completed when total erase
status command is received
Retransmits total erase status
command (H'3A) when H'11 is
received
If erase cannot be performed
when total erase status
command is received,
transmits H'EE to host and
halts operation
