Register descriptions
Each register is selected using address lines A0, A1, A2, and in some cases, bits from
other registers. The programming combinations for register selection are shown in
[1]
MCR[7] can only be modified when EFR[4] is set.
[2]
Accessed by a combination of address pins and register bits.
[3]
Accessible only when LCR[7] is logic 1.
[4]
Accessible only when LCR is set to 1011 1111 (BFh).
[5]
Accessible only when EFR[4] = logic 1 and MCR[6] = logic 1, i.e., EFR[4] and MCR[6] are read/write
enables.
[6]
Accessible only when CSA or CSB = logic 0, MCR[2] = logic 1, and loopback is disabled
(MCR[4] = logic 0).
