Registers addresses
3.1.25
34/51
MD11..0=1: The corresponding I/O doesn’t generate interrupt.
MD11..0=0: The corresponding I/O (programmed as Input) generate interrupt if a change of
status is detected.
Input lines with persistency check generate interrupt if the changed status remains stable
longer than the time programmed in the persistency check registers PCHKA/B. Lines
without persistence check generate an immediate interrupt request.
Mask register has no effect on those pins configured as outputs, those pins will not generate
interrupt.
Pin-strap value.
Interrupt Mask register for CD port (CMASK)
Addr=1Eh; Reset Value=XFh
In MCU mode, dynamic I/O configuration, MCn bits are the disable/enable interrupt related
to the channel n:
MC3..0= 0 Any I/O line of the related channel is enabled to generate interrupt depending on
DMASK setting.
MC3..0=1 Any I/O line of the related channel is disabled to generate interrupt independently
of DMASK setting.
In MCU mode, static I/O configuration, MCn bits are the interrupt mask bits related to CSn
that are configured as I/O lines.
MC3..0=1: The corresponding I/O doesn’t generate interrupt.
MC3..0=0: The corresponding I/O generate interrupt if a change of status is detected.
Input lines with persistency check generate interrupt if the changed status remains stable
longer than the time programmed in the persistency check registers PCHKA/B
Lines 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.
