Table 10
lists and describes the SC16C752 internal registers.
[1]
[2]
These registers are accessible only when LCR[7] = 0.
The shaded bits in the above table can only be modified if register bit EFR[4] is enabled, i.e., if enhanced functions are enabled.
Table 10:
Shaded bits are only accessible when EFR[4] is set.
