24. Serial Programming Instruction
The Instruction Set for Serial Programming follows a 4-byte protocol and is shown in Table 24-1.
After Reset signal is high, SCK should be low for at least 64 system clocks before it goes high to clock in the enable data
bytes. No pulsing of Reset signal is necessary. SCK should be no faster than 1/16 of the system clock at pin XTAL1.
For Page Read/Write, the data always starts from byte 0 to 31 or 63. After the command byte and upper address byte are
latched, each byte thereafter is treated as data until all 32 or 64 bytes are shifted in/out. Then the next instruction will be
ready to be decoded.
