6.6.2 Interrupt Control Functions
6.6.2.1 Enable a Board's Interrupt Source(s) - setIntMask
Enables or disables one or more of a board’s interrupt sources, by writing a mask byte to the
board's Interrupt Mask register. For the PC215E, PC212E, PC218E and PC272E boards, any
number of the interrupt sources can be enabled (a single interrupt is generated, but the
interrupt service routine interrogates each source in turn and, if asserted, services that
interrupt).
i = setIntMask (h, mask)
where
h Integer: Board handle as issued by the
registerBoard function.
mask Integer: Mask byte. The bit designations for
the board’s Interrupt Mask Register will vary
from board to board. Refer to section 5.3.21 for
a description of the interrupt sources, and their
functionality.
Returns Integer:
OK
or ERRHANDLE
ERRSUPPORT

disableInterrupts
6.6.2.2 Read a Board's Interrupt Source Status - getIntStat
Returns a board’s interrupt source status byte, by reading from the board's Interrupt Status
register. The status of each bit is returned, irrespective of whether it has been enabled using
the setIntMask function. See section 5.3.21 for a description of the interrupt sources.
i = getIntStat (h)
where
h Integer: Board handle as issued by the
registerBoard function.
Returns Integer:
Interrupt status byte. See section 2.6.4 for a description of the
interrupt sources.
