UART Control and Status Registers
A-126 ADSP-21368 SHARC Processor Hardware Reference
Scratch Registers (UARTxSCR)
The contents of the 8-bit UART scratch registers (UARTxSCR shown in
Figure A-55) is reset to 0x00. It is used for general-purpose data storage
and does not control the UART hardware in any way.
Mode Registers (UARTxMODE)
The UART mode registers control miscellaneous settings as shown in
Figure A-56 and described Table A-48.
