NOTE

All registers in this module are 8-bit registers that are connected to Peripheral Frame 2. When a register is accessed, the register data is in the lower byte (7–0), and the upper byte (15–8) is read as zeros. Writing to the upper byte has no effect.

Enhanced features:

•Auto baud-detect hardware logic

•16-level transmit/receive FIFO

The SCI port operation is configured and controlled by the registers listed in Table 4-8and Table 4-9.
