19.1
• Size: 256 kbytes
• Programming/erase methods
• Reprogramming capability
• Two on-board programming modes
• PROM Programmer mode
• Automatic bit rate adjustment
• Programming/erasing protection
 The flash memory is programmed 128 bytes at a time. Erase is performed in single-block
 For details, see section 25, Electrical Characteristics.
 Boot mode
 User program mode
 Flash memory can be programmed/erased in programmer mode using a PROM
 With data transfer in boot mode, this LSI's bit rate can be automatically adjusted to match
 Sets software protection against flash memory programming/erasing/verifying.
units. The flash memory is configured as follows: 64 kbytes × 3 blocks, 32 kbytes × 1
block, and 4 kbytes × 8 blocks. To erase the entire flash memory, each block must be
erased in turn.
On-board programming/erasing can be done in boot mode, in which the boot program built
into the chip is started to erase or program of the entire flash memory. In normal user
program mode, individual blocks can be erased or programmed on board.
