Stop Cycle Timing

3.3.1 Serial Interrupts (Slave Mode)

IRQ Sample Period is three clocks long, with the ﬁrst clock

being the Sampled phase, the second clock being the

Recovery phase, and the third clock being the Turn-around

phase. During the Sample phase the Serial Interrupt

device drives SERIRQ low if its associated IRQ signal/data

is presently low. If its IRQ signal/data is high the Serial

Interrupt device must TRI-STATE SERIRQ. During the

Recovery phase, the Serial Interrupt device that drove

SERIRQ low (if any Serial Interface device does) is

required to drive back high. During the Turn-around phase

all Serial Interface devices will TRI-STATE SERIRQ. All

Serial Interface devices will drive SERIRQ low at the

appropriate sample point regardless of which device initi-

ated the sample activity, if its associated IRQ signal/data is

low.

There are two types of Serial Interrupt transfer modes; the

following describes the operation of the PC87200’s Serial

Interrupt Interface as a Slave:

1. Quiet Mode: Any Serial Interrupt device may initiate a

Start Cycle, while the Serial Interrupt interface is Idle, by

driving SERIRQ low for one PCI clock period. After driv-

ing low for one clock the device should immediately TRI-

STATE^®SERIRQ, without ever driving this signal high.

A Start Cycle may not be initiated in the middle of an ac-

tive Serial Interrupt transfer. Between Stop and Start Cy-

cles the SERIRQ signal will be pulled high and the Serial

Interrupt interface will be Idle.

When the PC87200 Serial Interrupt interface must ini-

tiate a Start Cycle in order to transfer any pending inter- Slave

rupt request to the Master. The only exception to this

The PC87200 will support the interrupt request frames

listed in the following table.

requirement is when a Serial Interrupt transfer sequence

is already in progress and the PC87200 can transfer the

request during this present Serial Interrupt transfer se-

quence, then the Serial Interrupt device is not required to

generate another Start Cycle.

The Generation clock for each IRQ follows the low to high

edge of the Start Pulse by the number of PCI Clocks listed

in Table 1.

Note: : The number of clocks equals: (3 x (IRQ number + 1)) - 1

2. Continuous Mode: The PC87200 tracks both the Start

and Stop Frames and is responsible for inserting its in-

terrupt requests on the appropriate IRQ frames.

3.3.3 Stop Cycle Control

The PC87200 will monitor SERIRQ for a Stop Cycle, so

that it may initiate a Start Cycle for a pending transition in

any of its IRQs (Quiet Mode). For Continuous Mode, the

PC87200 will not initiate any Start Cycle, but will track the

Start and Stop Cycles and insert its IRQs appropriately.

3.3.2 IRQ Sampling Periods

Once a Start Cycle has been initiated all Serial Interrupt

devices watch for the rising edge of the Start Pulse and

start counting IRQ Sample periods from that point. Each
