External: N/C (low). PCI: N/C (low). ISA: connect to 3.3V. 2,3,4,5, 9,10,11, 12 UD0 - UD7 O Modem Control Output, for external modem: Memory address mapping of the controller is E800H. 8 RxDCLK I Receive Data Rate Clock:(External) This pin is used as reference clock of DSPRXD pin. 18 68 68 RD_SP2 I Data Input Pin Of The Serial Port 2: The serial data is sampled at the falling edge of the SCLK. The MSB is coming immediately after the falling of FR_SP2 signal. 19 TXDCLK I Transmit Data Rate Clock:(External) This pin is used as reference clock of DSPTXD pin. 21 DSPTxD I Modem Transmit Data (External) Shifted into Tx /Rx DSP from EIA port through this pin at the rising edge of TXDCLK. 28 69 69 RD_SP1 I Data Input Pin Of The Serial Port 1: The serial data is sampled at the falling edge of the SCLK. The MSB is coming immediately after the falling of FR_SP1 signal. 6,20,37 50,77,80, 89,107, 118,123 6,20,37 50,80,89 107,118, 123 6,20,37 50,77,80, 89,107, 118,123 GND P Ground 22, 23, 24, 25 OUTP3, OUTP2, OUTP1, OUTP0 O Modem Control Output For external modem, these pins are bit7~4 of the modem control output. Memory address mapping of the controller is C800H. 29, 30, 31, 32 INP3, INP2, INP1, INP0 I Modem Control Input:(External) These pins are bit3~0 of the modem control input. Memory address mapping of the controller is C800H. 33,45 67,94, 113,128 33,45, 67,94, 113,128 33,45, 67,94, 113,128 VDD P +3.3V Power Supply 13,74 13,74 13,74 VCC P +2.5V Power Supply 34 34 34 TEST2 I Test pin 2,normal ground 35 35 35 TEST3 I Test pin 3,normal ground 36 RESET I Reset: An active high signal used to reset the DM6588A. 42 42 42 XTAL1 I Crystal Oscillator Input |
