9.4.4 Insertion Points for ROM Correction Processing

TOP PREVIOUS NEXT

- Processing read-outs from EEPROM

  - RCaccE2PrSUB: Insert after port or control register setting (AC check).

    It is also necessary for the EEPROM’s power supply to be in power-off (AC positive).

- Processing Modifying Program Calls

  - RCtimerinsSUB: Insert at the end of the timer interrupt.

  - RCschedulerSUB: Insert in the OS scheduler.

  - RCinitialSUB: Insert after initialization, immediately before jumping to the main process.

  - RCstandbySUB: Insert immediately before the power failure process STP command.

  - RCimagetskSUB: Insert immediately before branching to individual image processing.

  - RCdisptskSUB: Insert immediately before processing the data settings for the display RAM.

  - Rcreserve0SUB: Insert in the transmission process to the CD mechanism component.

  - Rcreserve1SUB: Insert in the transmission process to the DSP control micro-controller.

- Data inside the EPROM (Required RAM capacity)

  - EEPROM flag indicator determination data: 10 bytes

  - Modifying Program’s starting address: 16 bytes

  - Modifying Program: remaining bytes
