DMA Controller
The direct memory access (DMA) controller provides an efficient way to move blocks of data with minimal processor
intervention. It has four channels that allow byte, word, longword, or 16-byte burst line transfers. These transfers are triggered
by software explicitly setting a DCRn[START] bit or by the occurrence of certain UART or DMA timer events.
1.2.21
Reset
The reset controller determines the source of reset, asserts the appropriate reset signals to the system, and keeps track of what
caused the last reset. There are seven sources of reset:
External reset input
Power-on reset (POR)
Watchdog timer
Phase locked-loop (PLL) loss of lock
PLL loss of clock
Software
Low-voltage detector (LVD)
Control of the LVD and its associated reset and interrupt are managed by the reset controller. Other registers provide status flags
indicating the last source of reset and a control bit for software assertion of the RSTO pin.
1.2.22
GPIO
Nearly all pins on the device have general purpose I/O capability and are grouped into 8-bit ports. Some ports do not use all
eight bits. Each port has registers that configure, monitor, and control the port pin.
1.2.23
Part Numbers and Packaging
