1.2.7
USB On-The-Go Controller
The device includes a Universal Serial Bus On-The-Go (USB OTG) dual-mode controller. USB is a popular standard for
connecting peripherals and portable consumer electronic devices such as digital cameras and handheld computers to host PCs.
The OTG supplement to the USB specification extends USB to peer-to-peer application, enabling devices to connect directly
to each other without the need for a PC. The dual-mode controller on the device can act as a USB OTG host and as a USB
device. It also supports full-speed and low-speed modes.
1.2.8
UARTs
The device has three full-duplex UARTs that function independently. The three UARTs can be clocked by the system bus clock,
eliminating the need for an external clock source. On smaller packages, the third UART is multiplexed with other digital I/O
functions.
1.2.9
I2C Bus
The I2C bus is an industry-standard, two-wire, bidirectional serial bus that provides a simple, efficient method of data exchange
and minimizes the interconnection between devices. This bus is suitable for applications requiring occasional communications
over a short distance between many devices.
1.2.10
QSPI
The queued serial peripheral interface (QSPI) provides a synchronous serial peripheral interface with queued transfer capability.
It allows up to 16 transfers to be queued at once, minimizing the need for CPU intervention between transfers.
1.2.11
Fast ADC
The fast ADC consists of an eight-channel input select multiplexer and two independent sample and hold (S/H) circuits feeding
separate 12-bit ADCs. The two separate converters store their results in accessible buffers for further processing.
The ADC can be configured to perform a single scan and halt, a scan when triggered, or a programmed scan sequence repeatedly
until manually stopped.
The ADC can be configured for sequential or simultaneous conversion. When configured for sequential conversions, up to eight
channels can be sampled and stored in any order specified by the channel list register. Both ADCs may be required during a
scan, depending on the inputs to be sampled.
During a simultaneous conversion, both S/H circuits are used to capture two different channels at the same time. This
configuration requires that a single channel may not be sampled by both S/H circuits simultaneously.
Optional interrupts can be generated at the end of the scan sequence if a channel is out of range (measures below the low
threshold limit or above the high threshold limit set in the limit registers) or at several different zero crossing conditions.
1.2.12
DMA Timers (DTIM0–DTIM3)
There are four independent, DMA transfer capable 32-bit timers (DTIM0, DTIM1, DTIM2, and DTIM3) on the device. Each
module incorporates a 32-bit timer with a separate register set for configuration and control. The timers can be configured to
operate from the system clock or from an external clock source using one of the DTINn signals. If the system clock is selected,
it can be divided by 16 or 1. The input clock is further divided by a user-programmable 8-bit prescaler that clocks the actual
timer counter register (TCRn). Each of these timers can be configured for input capture or reference (output) compare mode.
Timer events may optionally cause interrupt requests or DMA transfers.
