Power-down with RAMP-DOWN (PD2-A9H) or without RAMP-DOWN (PD1-E1H)
1. PDN1 will power-down the chip and set the COUT data to 00H immediately.
2. PDN2 will power-down the chip by Ramp-down the COUT from its current value to 00H.
3. Power-down will start after 350us (at 6KHz sampling rate).
4. The OUT1 pin (BUSY) will output logic HIGH during Ramp-down operation.
5. PDN2 (Power-down with ramp-down) will be executed correctly only if PU2 is
Set OUT2 pin status (STATUS-E3H)
1. Signal output from the pin, OUT2, is defined by G[3:0], as below:
2. If the STATUS is not executed, default value of OUT2 is the internal Reset signal.
3. BUSYB is the logical inversion of BUSY.
4. EMPTY (or FULLB) is the logical inversion of FULL.
5. Only the 1MHz clock will not be stopped by the PAUSE command.
