Table 17−3 lists the registers for all devices implementing a USART module.

Table 17−4 applies only to devices with a second USART module, USART1.

Note: Modifying SFR bits

To avoid modifying control bits of other modules, it is recommended to set

or clear the IEx and IFGx bits using BIS.B or BIC.B instructions, rather than

MOV.B or CLR.B instructions.
