GENERAL RELEASE SPECIFICATION

MOTOROLA
INTERRUPTS
MC68HC05CL48
4-4
REV 2.0
interrupt will occur as soon as the interrupt mask bit is cleared. The latch will be
cleared by RESET or cleared automatically during fetch of the EXTERNAL
Interrupt vectors. Therefore, one (and only one) external interrupt edge could be
latched during the interrupt mask bit is set.
The service routine address is specified by the contents of $FFFA and $FFFB.
Figure 4-2 shows both a block diagram and the two methods for the interrupt line
(IRQ) to the processor. The first method is single pulses on the interrupt line
spaced far enough apart to be serviced. The minimum time between pulses is a
function of the number of cycles required to execute the interrupt service routine
plus 21 cycles. Once a pulse occurs, the next pulse should not occur until the
MCU software has exited the routine (an RTI occurs). The second configuration
shows several interrupt line “wire-ANDed” to perform the interrupts at the
processor. Thus, if after servicing one interrupt and the interrupt line remains low,
then the next interrupt is recognized.
NOTE
INTO is located at bit-1 of the Option Register at $001F, and is set
by reset. The Option Register can only be written once after reset.
