The assigned bit functions are more fully defined in Section 7.1 through Section 7.11. [1] The value shown in represents the register’s initialized HEX value; X = n/a. [2] Accessible only when LCR[7] is logic 0. [3] Baud rate registers accessible only when LCR[7] is logic 1. [4] Enhanced Feature Register, Xon-1,2 and Xoff-1,2 are accessible only when LCR is set to ‘BFHex’. Table 7: SC16C2550 internal registers Shaded bits are only accessible when EFR[4] is set.
