† IA4 and FMT2 bits are only available in MODE 2 (I12, bit 6 = 1). In MODE1, IA4 is forced to 0.
* When in MODE 1, the playback base registers ( upper and lower) are used for both playback and capture.
§ In I8, MCE must be set to modify the lower 4 bits. MCE or PMCE must be set to modify the upper 4 bits.
In I9, MCE must be set to modify the upper 6 bits. PEN and CEN can be changed anytime.
In I16, MCE must be set to modify the serial port bits: SF1, SF0, and SPE.
In I28, MCE or CMCE must be set to modify the upper 4 bits.
