PRODUCT OVERVIEW
DMA Controller
Programmable I/O
·
2-channel General DMA for memory-to-
memory, memory-to-UART, UART-to-memory
data transfers without CPU intervention
·
·
18 programmable I/O ports
Pins individually configurable to input, output, or
I/O mode for dedicated signals
·
·
Initiated by a software or external DMA request
Interrupt Controller
Increments or decrements a source or
destination address in 8-bit, 16-bit or 32-bit data
transfers
·
21 interrupt sources, including 4 external
interrupt sources
·
4-data burst mode
·
·
Normal or fast interrupt mode (IRQ, FIQ)
Prioritized interrupt handling
UARTs
·
Two UART (serial I/O) blocks with DMA-based
or interrupt-based operation
PLL
·
The external clock can be multiplied by on-chip
·
Support for 5-bit, 6-bit, 7-bit, or 8-bit serial data
transmit and receive
PLL to provide high frequency system clock
·
·
The input frequency range is 10–40 MHz
·
·
·
·
·
·
·
Programmable baud rates
1 or 2 stop bits
The output frequency is 5 times of input clock.
To get 50 MHz, input clock frequency should be
10 MHz.
