43 / 92 page  Data Sheet AD9557 Rev. A | Page 43 of 92 The following changes write Register 0x0200 first and then issue an I/O update before writing the remaining M pin configuration registers in Register 0x0201 to Register 0x0208. The default EEPROM loading sequence from Register 0x0E10 to Register 0x0E16 is unchanged. The following steps must be inserted into the EEPROM storage sequence: 1. R0x0E17 = 0x00 # Write one byte 2. R0x0E18 = 0x02 # at Register 0x0200 3. R0x0E19 = 0x00 # 4. R0x0E1A = 0x80 # Op code for I/O Update R0x0E1B = 0x10 # Transfer 17 instead of 18 bytes 5. R0x0E1C = 0x02 # Transfer starts at Register address 6. R0x0E1D = 0x01 # 0x0201 instead of 0x0200 The rest of the EEPROM loading sequence is the same as the default EEPROM loading sequence, except that the register address of the EEPROM storage sequence is shifted down four bytes from the default. For example, • R0x0E1E = default value of Register 0x0E1A = 0x2E • R0x0E1F = default value of Register 0x0E1B = 0x03 • R0x0E20 = default value of Register 0x0E1C = 0x00 • … • R0x0E40 = default value of Register 0x0E1C = 0x3C = 0xFF • (end of data) |
