is required for retrieving error values on failures.
Inclusion of <
bsp/uart_rtems.h>
is required for accessing the uarts.
5.5.3.2. Parity, framing and overrun error notification
Upon receiving a parity, framing or an overrun error the read call returns 0 and the internal
RX queue is flushed.
5.5.4. Limitations
8 data bits only.
1 stop bit only.

5.6. Mass memory
5.6.1. Description
This section describes the mass memory driver’s design and usability.
This API represents the driver interface from a user application’s perspective f
or the RTEMS
driver.
The driver functionality is accessed through RTEMS POSIX API for ease of usage. In case
of failure on a function call,
errno
value is set for determining the cause.
