---help---
The LPC54xxx SPI supports data widths from 4 through 16 bits. For
data from 4 through 8 bits; the receive and transmit data is
represented with a uint8_t type. For the wider data, data is
represented with a uint16_t. There is duplication of logic for this
different widths. By default, SPI wide data is disabled since that
is the less frequently used data type and disabling wide data can
result in some size reduction. Select this option if you need wide
SPI data.

of this writing. Also added the netnsh configuration will, eventually,
be used to test the Ethernet driver.
2018-01-01: There Ethernet driver appears to be fully functional although
more testing is certainly needed. I believe that there is a memory
corruption issue in the current configuration that cause problems
occasionally. For example, after a longer Telnet session, I sometimes
see the following DEBUGASSERT after exiting the session from the host:
more testing is certainly needed.
2018-01-14: The basic SPI driver is code complete but still untested. It
is "basic" in the sense that it supports only polled mode (no DMA).
up_assert: Assertion failed at file:mm_heap/mm_free.c line: 129
which is a clear indication heap corruption. Increasing the size of some
stacks might correct this problem, but I have not yet experimented with
that. I have not seen the problem in any other context.
There is still no support for the Accelerometer, SPIFI, or USB. There is a
complete but not-yet-functional SD card. There is a partial SPI driver,
but no on-board SPI devices to test it.
There is still no support for the Accelerometer, SPIFI, or USB. There are
