3851 Group (Built-in 24 KB or more ROM)
(2) Parallel I/O Mode
Parallel I/O mode is the mode which parallel output and input soft-
ware command, address, and data required for the operations
(read, program, erase, etc.) to a built-in flash memory. Use the ex-
clusive external equipment flash programmer which supports the
3851 Group (flash memory version). Refer to each programmer
maker’s handling manual for the details of the usage.
User ROM and Boot ROM Areas
In parallel I/O mode, the user ROM and boot ROM areas shown in
Figure 57 can be rewritten. Both areas of flash memory can be oper-
ated on in the same way.
Program and block erase operations can be performed in the user ROM
area. The user ROM area and its block is shown in Figure 57.
The boot ROM area is 4 Kbytes in size. It is located at addresses
F00016 through FFFF16. Make sure program and block erase opera-
tions are always performed within this address range. (Access to any
location outside this address range is prohibited.)
In the Boot ROM area, an erase block operation is applied to only
one 4 Kbyte block. The boot ROM area has had a standard serial I/O
mode control program stored in it when shipped from the Renesas
factory. Therefore, using the device in standard serial I/O mode, you
do not need to write to the boot ROM area.
