Enables the Monitor data receive (MDR) interrupt status bit; MRE = 1
enables the Monitor data receive (MDR) and the Monitor end of
reception (MER) interrupt status bits
Masks the MDR and the MER bits
Enables the control of the MR bit internally by the IEC-Q according to
the Monitor channel protocol
Enforces a "1" (inactive state) in the Monitor channel receive (MR) bit
Combined with the MXC bit tied to "1" enable the Monitor channel data
acknowledged (MDA) and the Monitor channel data abort (MAB)
interrupt status bits
Masks the MDA and the MAB bits
Enables the control of the MX bit internally by the IEC-Q according to
the Monitor channel protocol
Enforces a "1" (inactive state) in the Monitor channel transmit (MX) bit
