5 / 18 page MC14LC5540 MOTOROLA 5 BCLKR Bit Clock, Receive (PDIP, SOG, TQFP—Pin 26) When used in the Long Frame Sync or Short Frame Sync mode, this pin accepts any bit clock frequency from 64 to 5120 kHz. This pin may be used for applying an external 256 kHz clock for sequencing the analog signal processing functions of this device. This is selected by the SCP port at BR0 (b7). FSR Frame Sync, Receive (PDIP, SOG, TQFP—Pin 27) When used in the Long Frame Sync or Short Frame Sync mode, this pin accepts an 8 kHz clock that synchronizes the input of the serial ADPCM data at the DR pin. FSR can oper- ate asynchronous to FST in the Long Frame Sync or Short Frame Sync mode. SERIAL CONTROL PORT INTERFACE PINS PDI/RESET Power–Down Input/Reset (PDIP, SOG—Pin 13; TQFP—Pin 11) A logic 0 applied to this input forces the device into a low– power dissipation mode. A rising edge on this pin causes power to be restored and the ADPCM Reset state (specified in the standards) to be forced. SCPEN Serial Control Port Enable Input (PDIP, SOG—Pin 14; TQFP—Pin 12) This pin, when held low, selects the Serial Control Port (SCP) for the transfer of control and status information into and out of the MC14LC5540 ADPCM Codec. This pin should be held low for a total of 16 periods of the SCPCLK signal in order for information to be transferred into or out of the MC14LC5540 ADPCM Codec. The timing relationship be- tween SCPEN and SCPCLK is shown in Figures 6 through 9. SCPCLK Serial Control Port Clock Input (PDIP, SOG—Pin 15; TQFP—Pin 13) This input to the device is used for controlling the rate of transfer of data into and out of the SCP Interface. Data are clocked into the MC14LC5540 ADPCM Codec from SCP Rx on rising edges of SCPCLK. Data are shifted out of the de- vice on SCP Tx on falling edges of SCPCLK. SCPCLK can be any frequency from 0 to 4.096 MHz. An SCP transaction takes place when SCPEN is brought low. Note that SCPCLK is ignored when SCPEN is high ( i.e., it may be continuous or it can operate in a burst mode). SCP Tx Serial Control Port Transmit Output (PDIP, SOG—Pin 16; TQFP—Pin 14) SCP Tx is used to output control and status information from the MC14LC5540 ADPCM Codec. Data are shifted out of SCP Tx on the falling edges of SCPCLK, most significant bit first. SCP Rx Serial Control Port Receive Input (PDIP, SOG—Pin 17; TQFP—Pin 15) SCP Rx is used to input control and status information to the MC14LC5540 ADPCM Codec. Data are shifted into the device on rising edges of SCPCLK. SCP Rx is ignored when data are being shifted out of SCP Tx or when SCPEN is high. |
