Determines the value of the MR bit:
0: MR bit always 1. In addition, the MDR0 interrupt is blocked, except for the first byte of a packet (if MRE=1).
1: MR internally controlled by the W6692 according to Monitor channel protocol. In addition, the MDR0
0: MX always 1.
1: MX internally controlled by the W6692 according to Monitor channel protocol.
Determines the value of the MX bit:
Monitor channel interrupt status MDR0, MER0 generation is enabled (1) or masked (0).
Monitor interrupt status MDA0, MAB0 generation is enabled (1) or masked (0).
