Once an interrupt subroutine is serviced, other
interrupts are all blocked (by clearing the EMI
bit). This scheme may prevent any further in-
terrupt nesting. Other interrupt requests may
take place during this interval, but only the in-
terrupt request flag will be recorded. If a cer-
tain interrupt requires servicing within the
service routine, the EMI bit and the correspond-
ing bit of the INTC0 or of INTC1 may be set in
ordertoallowinterruptnesting.Oncethestackis
full, the interrupt request will not be acknowl-
edged, even if the related interrupt is enabled,
untiltheSPisdecremented.Ifimmediateservice
isdesired,thestackshouldbepreventedfrombe-
coming full.
All these interrupts can support a wake-up
function. As an interrupt is serviced, a control
transfer occurs by pushing the contents of the
Register
