Page 9: Dma Support
DMA Support To allow fast data reception and transmission, the ComSync/104 supports four DMA channels; each one is assigned to one of the ESCC DMA Request pins. Each channel of the ESCC has 2 request pins which can be programmed as either a combined receive/transmit request or as separate receive and transmit requests (see the ESCC Users Manual for much more detail). -
Page 10: 85230 Register Bit Cloning
85230 Register Bit Cloning Various features of the ComSync/104 board are set up when certain register bits of the ESCC are programmed. This feature is extremely convenient and reduces the redundancy of setup functions. When certain bits are written to ESCC registers, the card keeps a copy of those bits to perform the setup of card features. -

Enable bit turned off. A false interrupt can be prevented in this way. Shared IRQ (Revision C and proceeding) The Selected IRQ can be shared between multiple ComSync/104 cards. This shared IRQ mechanism is designed using the guidelines in the PC/104 Specification V 2.5, appendix C. To enable Shared IRQ, turn On the Shared IRQ Enable bit I/O (8).0. -
Page 12: Software Selectable Line Interface Modes
Software Selectable Line Interface Modes The Serial Line Interface utilizes Sipex devices SP507 (on Revision A and B cards) or SP508 (on Revision C and proceeding cards). Refer to the data sheet for these devices for all electrical characteristics of the interface. The Line Interface Mode is software selectable for each Channel. -

Examples Half Duplex Setup To create this setup, both the RX-RTS Enable and TX-RTS Enable bits should be turned on, for the desired channel. For example: Bits 0 and 1 for Channel A, Bits 2 and 3 for Channel B. Multi-Drop To create this setup, only the TX-RTS Enable bit should be turned on, for the desired channel. -
Page 15: I/O Address And I/O Mode Setup
I/O Address and I/O Mode Setup The Base I/O Address and the I/O mode are selected via a miniature Dip Switch. When the Basic mode is selected the card only decodes eight consecutive addresses. If Enhanced Mode is used, then 64 consecutive addresses are used. The following are the selections: Table 8: I/O Address Selection Base I/O Address...
