SC16C754B
5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
Table 10
lists and describes the SC16C754B internal registers.
[1]
These registers are accessible only when LCR[7] = 0.
[2]
This bit can only be modified if register bit EFR[4] is enabled, that is, if enhanced functions are enabled.
[3]
The Special register set is accessible only when LCR[7] is set to a logic 1.
[4]
Enhanced feature register; Xon1/Xon2 and Xoff1/Xoff2 are accessible only when LCR is set to BFh.
