MCR[7] can only be modified when EFR[4] is set.
Accessed by a combination of address pins and register bits.
Accessible only when LCR[7] is logic 1.
Accessible only when LCR is set to 10111111 (xBF).
Accessible only when EFR[4] = 1 and MCR[6] = 1, i.e., EFR[4] and MCR[6] are read/write enables.
Accessible only when CSA - CSD = 0, MCR[2] = 1, and loop-back is disabled (MCR[4] = 0).
