PIC18F97J60 FAMILY
10.0
INTERRUPTS
Members of the PIC18F97J60 family of devices have
multiple interrupt sources and an interrupt priority feature
that allows most interrupt sources to be assigned a
high-priority level or a low-priority level. The high-priority
interrupt vector is at 0008h and the low-priority interrupt
vector is at 0018h. High-priority interrupt events will
interrupt any low-priority interrupts that may be in
progress.
There are thirteen registers which are used to control
interrupt operation. These registers are:
RCON
INTCON
INTCON2
INTCON3
PIR1, PIR2, PIR3
PIE1, PIE2, PIE3
IPR1, IPR2, IPR3
It is recommended that the Microchip header files
supplied with MPLAB IDE be used for the symbolic bit
names
in
these
registers.
This
allows
the
assembler/compiler to automatically take care of the
placement of these bits within the specified register.
In general, interrupt sources have three bits to control
their operation. They are:
Flag bit to indicate that an interrupt event
occurred
Enable bit that allows program execution to
branch to the interrupt vector address when the
flag bit is set
Priority bit to select high priority or low priority
The interrupt priority feature is enabled by setting the
IPEN bit (RCON<7>). When interrupt priority is enabled,
there are two bits which enable interrupts globally.
Setting the GIEH bit (INTCON<7>) enables all interrupts
that have the priority bit set (high priority). Setting the
GIEL bit (INTCON<6>) enables all interrupts that have
the priority bit cleared (low priority). When the interrupt
flag, enable bit and appropriate Global Interrupt Enable
bit are set, the interrupt will vector immediately to
address, 0008h or 0018h, depending on the priority bit
setting. Individual interrupts can be disabled through
their corresponding enable bits.
When the IPEN bit is cleared (default state), the
interrupt priority feature is disabled and interrupts are
compatible
with
PIC
mid-range
devices.
In
Compatibility mode, the interrupt priority bits for each
source have no effect. INTCON<6> is the PEIE bit
which enables/disables all peripheral interrupt sources.
INTCON<7> is the GIE bit which enables/disables all
interrupt sources. All interrupts branch to address,
0008h, in Compatibility mode.
When an interrupt is responded to, the Global Interrupt
Enable bit is cleared to disable further interrupts. If the
IPEN bit is cleared, this is the GIE bit. If interrupt priority
levels are used, this will be either the GIEH or GIEL bit.
High-priority
interrupt
sources
can
interrupt
a
low-priority interrupt. Low-priority interrupts are not
processed while high-priority interrupts are in progress.
The return address is pushed onto the stack and the
PC is loaded with the interrupt vector address (0008h
or 0018h). Once in the Interrupt Service Routine (ISR),
the source(s) of the interrupt can be determined by poll-
ing the interrupt flag bits. The interrupt flag bits must be
cleared in software before re-enabling interrupts to
avoid recursive interrupts.
The “return from interrupt” instruction, RETFIE, exits
the interrupt routine and sets the GIE bit (GIEH or GIEL
if priority levels are used) which re-enables interrupts.
For external interrupt events, such as the INTx pins or
the PORTB input change interrupt, the interrupt latency
will be three to four instruction cycles. The exact
latency is the same for one or two-cycle instructions.
Individual interrupt flag bits are set regardless of the
status of their corresponding enable bit or the GIE bit.
Note:
Do not use the MOVFF instruction to modify
any of the interrupt control registers while
any
interrupt is enabled. Doing so may
cause erratic microcontroller behavior.
