10 / 69 page 1–4 1.4 Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION AFC 11 O Automatic frequency control. The AFC DAC output provides the means to adjust system temperature-compensated reference oscillator (TCXO). AGC 10 O Automatic gain control. The AGC digital-to-analog converter (DAC) output can be used to control the gain of system receiver circuits. AVDDREF 3 — Analog supply voltage for FM receive path. Power applied to AVDDREF powers the FM receive path circuitry. AVDDRX 7 — Analog supply voltage for receive path. Power applied to AVDDRX powers the receive path circuitry. AVDDTX 19 — Analog supply voltage for transmit path. Power applied to AVDDTX powers the transmit path circuitry. AVSSREF 98 — Analog ground for REFCAP AVSSRX 12 — Analog ground for receive path AVSSTX 22 — Analog ground for transmit path BAT 1 I Battery strength monitor. A sample of the battery voltage is applied to BAT, and this sample monitors the battery strength. CINT 77 O Controller data interrupt. CINT is the microcontroller data interrupt (active low) signal that is sent to the DSP. CINT is caused by a microcontroller write to the Send-C interrupt register location. CMCLK 92 O Codec master clock. CMCLK provides a 2.048-MHz clock that is used as the master clock and bit clock for the speech codec. CSCLK 93 O Codec sample clock. CSCLK provides an 8-kHz frame synchronization pulse for the speech codec. CSCLK is also connected to the DSP for speech sample interrupts. DINT 49 O Microcontroller interrupt request. DINT is output when the DSP writes to the SEND DINT register location. DINT can be active high or low according to the levels of the MTS0 and MTS1 signals. DSPA0 74 I DSP 4-bit parallel address bus. DSPA0 through DSPA3 provides the address bus for DSPA1 73 the DSP interface. DSPA3 is the MSB, and DSPA0 is the LSB. DSPA2 72 DSPA3 71 DSPCSL 70 I DSP chip select (active low). A low signal at DSPCSL enables the specific DSP addressed. DSPD0 80 I/O/Z DSP 10-bit parallel data bus. DSPD0 through DSPD9 provide a 10-bit data bus for the DSPD1 81 DSP. DSPD9 is the MSB, and DSPD0 is the LSB. DSPD2 82 DSPD3 83 DSPD4 84 DSPD5 85 DSPD6 86 DSPD7 87 DSPD8 88 DSPD9 89 † Z = high impedance |
