7.2 Flash Memory Programming Function
The flash memory is written by transferring or receiving commands and data in a selected communication mode.
The major functions of flush memory programming are listed in Table 7-2.

Function
Description
Batch erasure
Erases all contents of memory.
Block erasure
Erases contents of specified memory block with one memory block consisting
of 16K bytes.
Batch blank check
Checks erased status of entire memory.
Block blank check
Checks erased status of specified block
Data write
Writes flash memory based on write start address and number of data to be
written (in bytes).
Batch verify
Compares all contents of memory with input data.
Block verify
Compares contents of specified memory block with input data.
7.3 Connecting Flashpro II
The Flashpro II and
μ
PD78F4218 are connected differently depending on the selected communication mode (3-
wire serial I/O or UART). Figures 7-2 and 7-3 show the connections in the respective communication modes.
