The information flags, which control the entire interrupt system, are stored in following
special function registers:
IE
Interrupt Enable Register
IP0
Interrupt Priority Register 1
IP1
Interrupt Priority Register 2
IRCON
Interrupt Control
TCON
Timer/Counter Control Register
SCON
Serial Control Register
TTXSIR
Sync Interrupt Request Register
ACQSIR
Acquisition Sync Interrupt Register C0
H
ADCON
ADC-Control Register
The interrupt system is shown diagrammatically in
Figure 23
.
A source requests an interrupt by setting its associated interrupt request flag in the
TCON, SCON, TTXSIR, ACQSIR or ADCON- register, as described in detail in
Table 15
.
