Register descriptions
Table 8 details the assigned bit functions for the seventeen SC16C650B internal registers.
The assigned bit functions are more fully dened in Section 7.1 through Section 7.11.
[1]
The value shown represents the register’s initialized HEX value; X = n/a.
[2]
These registers are accessible only when LCR[7] = 0.
[3]
These bits are only accessible when EFR[4] is set.
[4]
This function is not supported in the HVQFN32 package, and should not be written.
[5]
OUT2 pin is not supported in the HVQFN32 package, and this bit should not be written.
