Notes:
1.
Since Result Registers follow State Registers for interrupt transfers, the register offset starting value
shown in Table 16 for Result Registers follows the last value of Table 15 State Registers.
2.
The number of Result Register bytes returned will vary depending on the number of communication
command error conditions encountered or whether an iButton device was attached/detected.
