The following table explains the parameters used in Figure 13-2.
The two SPD0R registers have special functionality not shared by the other data registers.
If the master writes to SPD0R, an inbound interrupt flip-flop is set. If slave port interrupts
are enabled, the slave processor will take a slave port interrupt. If the slave writes to the
other SPD0R register, the slave attention line (/SLAVEATTN, pin 100) is asserted (driven
low) by the slave processor. This line can be used to create an interrupt in the master.
Either side that is interrupted can clear the signal that is causing an interrupt request by writ-
ing to the slave port status register. The data bits are ignored, but the flip-flop that is the
source of the interrupt request is cleared. Figure 13-3 shows a logical schematic of this func-
tionality.
