Functional overview
STR91xF
26/72
SRAM, handling of transmission requests, and interrupt generation. The CPU has access to
the Message SRAM via the Message Handler using a set of 38 control registers.
The follow features are supported by the CAN interface:
●
Bitrates up to 1 Mbps
●
Disable Automatic Retransmission mode for Time Triggered CAN applications
●
32 Message Objects
●
Each Message Object has its own Identifier Mask
●
Programmable FIFO mode
●
Programmable loopback mode for self-test operation
The CAN interface is not supported by DMA.
2.20
UART interfaces with DMA
The STR91xF supports three independent UART serial interfaces, designated UART0, UART1,
and UART2. Each interface is very similar to the industry-standard 16C550 UART device. All
three UART channels support IrDA encoding/decoding, requiring only an external LED
transceiver to pins UARTx_RX and UARTx_Tx for communication. One UART channel
(UART0) supports full modem control signals.
UART interfaces include the following features:
●
Maximum baud rate of 460.8 Kbps
●
Separate FIFOs for transmit and receive, each 16 deep, each FIFO can be disabled by
firmware if desired
●
Programmable FIFO trigger levels between 1/8 and 7/8
●
Programmable baud rate generator based on CCU master clock, or CCU master clock
divided by two
●
Programmable serial data lengths of 5, 6, 7, or 8 bits with start bit and 1 or 2 stop bits
●
Programmable selection of even, odd, or no-parity bit generation and detection
●
False start-bit detection
●
Line break generation and detection
●
Support of IrDA SIR ENDEC functions for data rates of up to 115.2K bps
●
IrDA bit duration selection of 3/16 or low-power (1.14 to 2.23 sec)
●
Channel UART0 supports modem control functions CTS, DCD, DSR, RTS, DTR, and RI
For your reference, only two standard 16550 UART features are not supported, 1.5 stop bits
and independent receive clock.
2.20.1 DMA
A programmable DMA channel may be assigned by CPU firmware to service channels UART0
and UART1 for fast and direct transfers between the UART bus and SRAM with little CPU
involvement. Both DMA single-transfers and DMA burst-transfers are supported for transmit
and receive. Burst transfers require that UART FIFOs are enabled.
