RESET REGISTER
The reset register is addressed by setting the address byte of the
input shift register to 0x56. The reset register contains a single
reset bit at Position DB0, as shown in Table 16. Writing a logic
high to this bit performs a reset operation, restoring the part to
its power-on state.
STATUS REGISTER
The status register is a read-only register. The status register bit
functionality is shown in Table 15 and Table 17.
