Register descriptions
The programming combinations for register selection are shown in Table 9.
[1]
MCR[7] can only be modified when EFR[4] is set.
[2]
Accessible only when ERF[4] = 1 and MCR[2] = 1, that is, EFR[4] and MCR[2] are read/write enables.
[3]
Accessible only when LCR[7] is logic 1.
[4]
Accessible only when LCR is set to 1011 1111b (0xBF).
