Product Specification

MPU Timing Description

This section contains timing diagrams for the MPU interface. Parameters used in the timing diagrams are described in

Tabl e 7 .

Single Register Read Cycle

The single register read cycle is shown in Figure 9,

page 13. A single register read is accomplished by assert-

ing a valid address (MPA), asserting the chip enable (MPCE

= LOW) and de-asserting the write enable (MPWE = HIGH)

during the first clock cycle (Cycle 0). These signals should

hold these values at least until the rising edge of the fourth

clock cycle (Cycle 3).

The output enable signal should be asserted (MPOE

LOW) during the third clock cycle (Cycle 2). Register data

associated with the specified address appears on the MPD

bus two clock cycles after the falling edge of MPCE

during

the assertion of MPCE

. The register read cycle is then com-

pleted by de-asserting the output enable during the fourth

clock cycle (Cycle 3).

MPWE

1InLOW

Synchronous active LOW write enable. A high-to-low-to-high transition must

occur on MPWE

in three consecutive clock cycles in order for the write to take

place.During a valid write cycle, MPCE

must be LOW and MPD must be valid

during the clock cycle that MPWE

MPOE

1InLOW

Asynchronous active LOW output enable. Both MPOE

and MPCE must be

LOW to read from the MPU interface. When either MPOE

or MPCE is HIGH,

the MPD pins of the System ACE CF controller are in a high-impedance state.

MPBRDY 1 Out HIGH

Synchronous active HIGH buffer ready output. During data buffer read mode

MPBRDY is HIGH when the data in the DATABUF buffer is valid. During data

buffer write mode MPBRDY is HIGH when data can be written to the

DATABUF buffer.

MPIRQ 1 Out HIGH

Synchronous active HIGH interrupt request output. MPIRQ HIGH indicates

that an interrupt condition has occurred in the MPU interface. All interrupt

conditions must be manually cleared before MPIRQ will go LOW. MPIRQ is

always LOW when interrupts are disabled.
