target baud rates are also possible. Note that because only integer values can be used as divisors, the actual
baud rate differs slightly from the desired (target) baud rate; for this reason, both target and actual baud
rates are given, along with the percentage of error.

The UIER gives the user the ability to mask specific UART interrupts to the programmable interrupt
controller (PIC).
