* defined by struct spi_ops_s (see include/nuttx/spi.h). All other methods
* including up_spiinitialize()) are provided by common PIC32MX logic. To use
* this common SPI logic on your board:
*
* 1. Provide logic in pic32mx_boardinitialize() to configure SPI/SSP chip select
* pins.
* 2. Provide pic32mx_spiNselect() and pic32mx_spiNstatus() functions
* in your board-specific logic. These functions will perform chip selection
* and status operations using GPIOs in the way your board is configured.
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
* pic32mx_spiNcmddata() functions in your board-specific logic. These
* functions will perform cmd/data selection operations using GPIOs in the way
* your board is configured.
* 3. Add a call to up_spiinitialize() in your low level application
* initialization logic
* 4. The handle returned by up_spiinitialize() may then be used to bind the
* SPI driver to higher level logic (e.g., calling
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
* the SPI MMC/SD driver).

* When designing a self powered (as opposed to bus powered) USB peripheral

* or D- pull up resistor unless Vbus is actively powered. Therefore, the
* firmware needs some means to detect when Vbus is being powered by the host.
* A 5V tolerant I/O pin can be connected to Vbus (through a resistor), and
* can be used to detect when Vbus is high (host actively powering), or low
* (host is shut down or otherwise not supplying power). The USB firmware
* can then periodically poll this I/O pin to know when it is okay to turn on
* the USB module/D+/D- pull up resistor. When designing a purely bus powered
* peripheral device, it is not possible to source current on D+ or D- when the

/* Record types:
*
* 00, data record, contains data and 16-bit address. The format described
* above.
* 01, End Of File record, a file termination record. No data. Has to be
* the last line of the file, only one per file permitted. Usually
* ':00000001FF'. Originally the End Of File record could contain a
* start address for the program being loaded, e.g. :00AB2F0125
* would make a jump to address AB2F. This was convenient when programs
* were loaded from punched paper tape.
* 02, Extended Segment Address Record, segment-base address. Used when 16
* bits are not enough, identical to 80x86 real mode addressing. The
* address specified by the 02 record is multiplied by 16 (shifted 4
* bits left) and added to the subsequent 00 record addresses. This
* allows addressing of up to a megabyte of address space. The address
* field of this record has to be 0000, the byte count is 02 (the segment
* is 16-bit). The least significant hex digit of the segment address is
* always 0.
* 03, Start Segment Address Record. For 80x86 processors, it specifies the
* initial content of the CS:IP registers. The address field is 0000, the
* byte count is 04, the first two bytes are the CS value, the latter two
* are the IP value.
* 04, Extended Linear Address Record, allowing for fully 32 bit addressing.
* The address field is 0000, the byte count is 02. The two data bytes
* represent the upper 16 bits of the 32 bit address, when combined with
* the address of the 00 type record.
* 05, Start Linear Address Record. The address field is 0000, the byte
* count is 04. The 4 data bytes represent the 32-bit value loaded into
* the EIP register of the 80386 and higher CPU.
