QSCI1 Additional Receive Operation Features
Additional QSCI1 features include:
•
Available on a single SCI channel (SCI1) implemented by the queue receiver enable (QRE) bit set
by software. When the queue is enabled, software should ignore the RDRF bit.
•
When the queue is disabled (QRE = 0), the SCI functions in single buffer receive mode (as
originally designed) and RDRF and OR function as previously defined. Locations SCRQ[0:15] can
