PROM PROGRAMMING AND OPERATING MODE

The E0C63P366 has built-in Flash EEPROMs as the code ROM and the segment option ROM that allow the

developer to program the ROM data using the exclusive PROM writer (UNIVERSAL ROM WRITER II). To create

data to be written to the code ROM, use the E0C63 assembler similar to the E0C63358/E0C63158. To create

data to be written to the segment option ROM use the segment option generator SOG63358 similar to the

E0C63358. Refer to "E0C63358 Development Tool Manual", for the SOG63358. This section explains the PROM

programmer that controls data writing and the writing mode.

The PROM programmer supports the following two writing modes.

1) Serial Programming

2) Parallel Programming

Serial Programming mode uses the serial communication ports of the PROM writer and E0C63P366 to write

data. This mode enables on-board programming by designing the target board with a serial writing function. In

Parallel Programming mode, the on-chip Flash ROM can be directly programmed using the exclusive PROM

writer with the adaptor socket installed. Refer to "Operating Mode" for each programming method.

Terminals

The E0C63P366 provides the following terminals for programming the Flash EEPROM.

SPRG

Flash programming control terminal (pull-up resistor built-in)

When set to High Normal operation mode (The CPU executes the program in the Flash EEPROM.)

When set to Low Programming mode (for writing data to the Flash EEPROM)

Serial transfer clock input/output terminal for Serial Programming (pull-up resistor built-in)

Serial data input terminal for Serial Programming (pull-up resistor built-in)

Serial data output terminal for Serial Programming

PROM programmer clock input terminal (1MHz; pull-up resistor built-in)

CLKIN

The five terminals above are provided exclusively for the Flash EEPROM. The E0C63358 and E0C63158 do not

have these terminals.
