This bit appears at the VOXCTL pin (Pin 5) of the SA5753. HPDN = enable power down of compandor circuit. This bit appears at the HPDN pin (Pin 6) of the SA5753 S4 = enable DTMF to TX path and inhibit PREMPIN and S2. S1 = bypass TXBPF S2 = bypass compressor in TX path, inhibit pre-emph input S12 = cordless data option established S5 = bypass RXBPF S6 = bypass de-emph in RX path S7 = bypass expandor in RX path, inhibit audio input S8 = enable DTMF to RX path and inhibit AUDIOIN and S7. S9 = enable SPKROUT S10 = enable EAROUT S11 = bypass TXLPF S13 = enable data path Register Bits B7 B6 B5 B4 B3 B2 B1 B0 S3 = bypass pre-emp and limiter in Tx path PWDN 1 0 0 0 0 IDLE1 X 1 1 0 0 IDLE0 X 0 1 0 1 (PWDN) Complete power down except I2C, I/Os high impedance. (DENA) Low power, I/Os at VDD/2, DATAIN to TXOUT enabled. (IDLE) Low power, I/Os at VDD/2, DATAIN to TXOUT disabled. Normal operation. DATAIN to TXOUT disabled. X = don’t care. Low Power Modes (R6B0 – R6B2) PWDN, IDLE1, IDLE0 see Table below Y Y Y Y Y = ignored in address mode. SR00667 |
