7 / 40 page DM336P V.34 Integrated Data/ Fax/Voice/Speakerphone Modem Device Set Final 7 Version: DM336P-DS-F02 August 15, 2000 DM6383 Pin Description (continued) Pin No. Pin Name I/O Description 47 P0.0 O Modem Control Output (memory map is bit 4 of DAA) 53 RXD I Controller Serial Port Data Input 54 TXD O Controller Serial Port Data Output 55 ALE/P O Controller Address Latch Enable: Output pulse for latching the low byte of the address during accesses to the external memory. 56 /PSEN O Controller Program Store Enable: This output goes low during a fetch from external program memory. 57 /WR O Controller External Data Memory Write Control 58 /RD O Controller External Data Memory Read Control 59 IRQ3 O Interrupt Request (see description of pin 26) 60 - 67 CA15 - CA8 O Controller Address Bus 69 - 76 CA7 - CA0 O Controller Address Bus 77 - 84 D7 - D0 I/O Controller Data Bus 86 TXRCLK I Transmitter Baud Rate Clock Input (Controller INT 0) 87 RXRCLK I Receiver Baud Rate Clock Input (Controller INT 1) 88 /POR O DSP Reset Output 89, 90 SEL1, SEL2 O Modem Control Output (Memory map is bit 1-2 of DAA at memory address D000H) 91 - 94 A12 - A15 I System Address: These signals are connected to the bus of the PC I/O slot. They are used to select the DM6383 I/O ports. 95 /PNPEN I PnP Mode Enable: This pin will be detected to enable/disable the PnP mode. When it is pulled down by a resistor (3.3K ~ 4.7K), the DM6383 can enter the PnP mode when it receives the PnP initial key sequence. When disconnected, an internal pull up will disable the Plug and Play function. 97 /TUCS O TX DSP Register Select Output: Memory address mapping of the controller is F000H. 98 PS1 O Modem Control Port Select Output: Memory address mapping of the controller is D800H. 99 TEST1 I Test Pin: Used for system configuration and test mode TEST2 0 0 1 1 TEST1 0 1 0 1 System Configuartion Internal mode External mode Test mode Test mode |
