Introduction
1.6.2.8 Interrupt Cascading
The ESCC2 supports two cascading schemes which can be selected by programming
the IPC register:
Slave Mode
Interrupt outputs of several devices (slaves) are connected to a priority resolving unit
(e.g. interrupt controller). The slave which is selected for the interrupt service routine is
addressed via special address lines during the interrupt acknowledge cycle. For this
application the ESCC2 offers two Interrupt Enable inputs (IE0, IE1) and a programmable
2-bit slave ID.

For Intel type microprocessor systems the 2-cycle interrupt acknowledge scheme is
supported (‘86 mode).
