Interrupt mask register for I/O port (DMASK)
Addr=11h; reset value=FFh
Addr=12h; reset value=XFh
Table 26.
Table 27.

Input lines with persistency check generate interrupt if the changed status remains stable
longer than the time programmed in the persistency check register PCHKA/B. Line without
persistency check generate an immediate interrupt request.
Mask register has no effect on those pins configured as outputs, those pins will not generate
interrupt.
Interrupt mask register for interrupt (IMASK)
Addr=13h; reset value=FFh
Table 28.
For dynamic I/O configuration, MCn bits are the disable/enable interrupt related to the
channel n.

change of status is detected.
MC3..0=1: Any I/O line of the related channel #n is disabled to generate interrupt
independently of DMASK setting.
MC3..0=0: Any I/O line of the related channel #n is enabled to generate interrupt
depending on DMASK setting.
