Section 21 Flash Memory (0.18-μm F-ZTAT Version)
21.7
Along with its on-board programming mode, this LSI also has a PROM mode as a further mode
for the writing and erasing of programs and data. In the PROM mode, a general-purpose PROM
programmer can freely be used to write programs to the on-chip ROM. Program/erase is possible
on the user MAT and user boot MAT. The PROM programmer must support Renesas
microcomputers with 512-kbyte flash memory as a device type.
A status-polling system is adopted for operation in automatic program, automatic erase, and
status-read modes. In the status-read mode, details of the system’s internal signals are output after
execution of automatic programming or automatic erasure. In the PROM mode, provide a 12-MHz
input-clock signal.
21.8
Initiating boot mode enables the boot program to communicate with the host by using the internal
SCI. The serial communication interface specification is shown below.
(1)
The boot program has three states.
1. Bit-Rate-Adjustment State
2. Inquiry/Selection State
3. Programming/erasing state
These boot program states are shown in figure 21.17.

REJ09B0109-0700
In this state, the boot program adjusts the bit rate to communicate with the host. Initiating boot
mode enables starting of the boot program and entry to the bit-rate-adjustment state. The
program receives the command from the host to adjust the bit rate. After adjusting the bit rate,
the program enters the inquiry/selection state.
In this state, the boot program responds to inquiry commands from the host. The device name,
clock mode, and bit rate are selected. After selection of these settings, the program is made to
enter the programming/erasing state by the command for a transition to the
programming/erasing state. The program transfers the libraries required for erasure to the
RAM and erases the user MATs and user boot MATs before the transition.
Programming and erasure by the boot program take place in this state. The boot program is
made to transfer the programming/erasing programs to the RAM by commands from the host.
Sum checks and blank checks are executed by sending these commands from the host.
