MASK-Register
The Interrupt Mask Register (MASK) can selectively mask each interrupt source in the
ISTA register by setting to “1“ the corresponding bit.

B2-channel Interrupt
B2 = 1 indicates an interrupt every time B2-channel bytes arrive.
B2 = 0 occurs after RB2I and RB2U have been read.
Monitor Data Transmit Interrupt
MDA = 1 indicates an interrupt after the MOSR:MDA or the
MOSR:MAB bits have been activated.
MDA = 0 indicates the inactive interrupt status.
D-channel mask
D = 1 prevents an interrupt ISTA:D to actually influence the INT
pin.
D = 0 disables the function described above.
CICI-channel mask
CICI = 1 prevents an interrupt ISTA:CICI to actually influence the
INT pin.
CICI = 0 disables the function described above.
CICU-channel mask
CICU = 1 prevents an interrupt ISTA:CICU to actually influence
the INT pin.
CICU = 0 disables the function described above.
Superframe marker mask
SF = 1 prevents an interrupt ISTA:SF to actually influence the INT
pin.
SF = 0 disables the function described above.
