If the computer in which the MPAP-100 is installed is running PCMCIA Card andSocket Services, the bas...
Page 28 - Interrupts; further interrupt servicing if necessary.
8 Interrupts The MPAP-100 will operate using the interrupt level (IRQ) assigned by the PCMCIA system. Interrupts can come from the SCC, the external FIFOs or RS-232 test mode. Theinterrupt source is selected by bits 4 and 5 of the Configuration Register (see page 41). When using interrupts with the ...

10.4.2 Resetting the FIFOs The FIFOs are automatically disabled and reset at powerup or when the MPAP-100 is inserted into a PCMCIA socket. The transmit and receive FIFOs can also be independently resetby setting and clearing the appropriate bits in the FIFO Control Register. Resetting a FIFO setsth...
Page 42 - NOTE; While most useful in byte-synchronous modes, the
To make the external FIFOs more useful in byte-synchronous modes, the MPAP-100 can watch for a given character to be transferred consecutively a specific number of times from theSCC into the receive FIFO. When this occurs, the RX_PAT bit in the Interrupt Status Register(see page 43) is set. For inst...
