McBSP FIFO Status Register
DRR2/DRR1 and DXR2/DXR1 share the same addresses of receive and transmit FIFO registers in FIFO mode.
FIFO pointers advancing is based on order of access to DRR2/DRR1 and DXR2/DXR1 registers.

Serial Communications Interface (SCI) Module
R281x devices include two serial communications interface (SCI) modules. The SCI modules support digital
communications between the CPU and other asynchronous peripherals that use the standard
non-return-to-zero (NRZ) format. The SCI receiver and transmitter are double-buffered, and each has its own
separate enable and interrupt bits. Both can be operated independently or simultaneously in the full-duplex
mode. To ensure data integrity, the SCI checks received data for break detection, parity, overrun, and framing
errors. The bit rate is programmable to over 65000 different speeds through a 16-bit baud-select register.
Features of each SCI module include:
Two external pins:
SCITXD: SCI transmit-output pin
SCIRXD: SCI receive-input pin
NOTE:
Both pins can be used as GPIO if not used for SCI.
