46 / 178 page  FEDL22Q53X-02 ML22Q53X ● Flash memory rewrite function The flash memory can be rewritten in the following two ways. ① Rewrite using the clock synchronous serial interface of the MCU command interface By using the CSB, SCK, SI and SO pins, which are clock synchronous serial interfaces of the MCU command interface the flash memory can be rewritten. When the PUP command and FDIRECT command are entered with the IRON pin set to "L", direct access to the flash memory is enabled from the CSB, SCK, SI and SO pins. When returning to the normal mode, insert a reset to initialize (RESETB pin is “L” level.) or shut off the power. For the PUP command, refer to the "PUP command" in the "Command" section. For the FDIRECT command, refer to the "FDIRECT command" in the "Command" section. ② Rewrite using flash memory interface The flash memory can be rewritten using the IRON, IRCSB, IRSCK, IRSI and IRSO pins that is the flash memory interface. When the PUP command and FDIRECT command are entered with the IRON pin set to "H", direct access to the flash memory is enabled from the IRCSB, IRSCK, IRSI and IRSO pins. When returning to the normal mode, insert a reset to initialize (RESETB pin is “L” level.) or shut off the power. For the PUP command, refer to the "PUP command" in the "Command" section. For the FDIRECT command, refer to the "FDIRECTcommand" in the "Command" section. The Chip Erase, Status Read, Program and Read of the flash memory are described on the next page.
