port, any of the following actions can be per-

formed:

1) Drive the CS pin low [or if CS pin is already

low, drive the pin high, then back to low].

2) Hardware Reset (drive RESET pin low, for at

least 10 µs).

3) Issue the Serial Port Initialization Sequence,

which is performed by clocking 3 (or more)

SYNC1 command bytes (0xFF) followed by

one SYNC0 command byte (0xFE).

6.6 CS5461 Power States

Active state denotes the operation of CS5461 when

the device is fully powered on (not in sleep state or

stand-by state). To insure that the CS5461 is oper-

ating in the active state; perform one of the three

actions below:

1) Power on the CS5461. (Or if the device is al-

ready powered on, recycle the power.)

2) Software Reset

3) Hardware Reset

If the device is in sleep state or in stand-by state, is-

suing the Power-Up/Halt command will also insure

that the device is in active state. In order to send the

Power-Up/Halt command to the device, the serial

port must be initialized. Therefore, after applying

power to the CS5461, a hardware reset should al-

ways be performed.
