MT9079

CMOS ST-BUS™ FAMILY Advanced Controller for E1

Mitel Networks 

MT9079

the interrupt vector is read it is automatically cleared

and IRQ will return to a high impedance state. In

ST-BUS mode, as well as processor and controller

modes, this function is accomplished by toggling the

INTA bit (page 1, address 1AH.)

All the interrupts of the MT9079 are maskable. This is

accomplished through interrupt mask words zero to

four, which are located on page 1, addresses 1BH to

1EH.

After a MT9079 reset (RESET pin or RST control bit)

all interrupts of mask words one, two and three are

masked; and the interrupts of mask word zero are

unmasked.

All interrupts may be suspended, without changing

the interrupt mask words, by making the SPND

control bit of page 1, address 1AH high.
