Function
Description
Reset
Detects write stop and transmission synchronization.
Batch verify
Compares entire memory contents and input data.
Batch delete
Deletes the entire memory contents.
Batch blank check
Checks the deletion status of the entire memory.
High-speed write
Performs writing to flash memory according to write start address and number of write data
(bytes).
Continuous write
Performs successive write operations using the data input with high-speed write operation.
Status
Checks the current operation mode and operation end.
Oscillation frequency setting
Inputs the resonator oscillation frequency information.
Delete time setting
Inputs the memory delete time.
Baud rate setting
Sets the transmission rate when the UART method is used.
Silicon signature read
Outputs the device name, memory capacity, and device block information.
22.2.3 Flashpro II connection
Connection of Flashpro II and the
µ
PD78F0974 differs depending on transmission method (3-wire serial I/O, UART,
and pseudo 3-wire serial I/O). Each case of connection shows in Figures 22-3, 22-4, and 22-5.
