NRZ (non-return-to-zero) format
Ten SCI module control registers located in the control register frame beginning at address 7050h
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 48 and Table 49.

Shaded registers are new registers for the FIFO mode.
Registers in this table are mapped to peripheral bus 16 space. This space only allows 16-bit accesses. 32-bit accesses produce undefined results.
