26.2 Common SMC Settings and ConÞgurations
The following sections describe settings and conÞgurations that are common to the SMCs.
26.2.1 SMC Mode Registers (SMCMR1/SMCMR2)
The SMC mode registers (SMCMR1 and SMCMR2), shown in Figure 26-2, selects the
SMC mode as well as mode-speciÞc parameters. The functions of SMCMR[8Ð15] are the
same for each protocol. Bits 0Ð7 vary according to protocol selected by the SM bits.
