2.2.1 Steps

  1. Dummy stack write registers OTP_ECC_DATAIN1 to OTP_ECC_DATAIN8 = 0x00 to sync the DLL (delay-locked loop). These are 8 stack write commands.

  2. Broadcast write to enable auto-addressing mode (CONTROL1=0x01).

  3. Broadcast write consecutively to DIR0_ADDR = 0, 1, 2, 3 (register address 0x306).

  4. Broadcast write to set all devices as stack device first (COMM_CTRL=0x02).

  5. Single device write to the highest device in the stack to configure it as both stack and top of stack (COMM_CTRL=0x03).

  6. Dummy stack read registers OTP_ECC_DATAIN1 to OTP_ECC_DATAIN8 to sync the DLL. These are 8 stack read commands.
