--------------------- EEPROM emulation headers  -----------------------
EEPROM emulator is used to store the irrigation programs in FLASH. Total of 4
programs can be stored USER-A, USER-B, USER-C and Contractor. The 3 User programs
can be recalled at any time by placing to Program Select switch in proper position.
The Contractor program is only accessible through "SAVE" and "RESTORE" functions
of the "Spetial Features" user interface menu.

/*
笔记:
模拟1k，实际需要2k空间(2页交互使用)
能保存1k/2=512byte数据(另外512byte存地址)
注意:数据越小越好建议在1k/4=256byte内，这样才有意义
<=256byte, 用1k
<=512byte, 用2k
