Functional Description and Application Information
— Exact match for single 48-bit individual (unicast) address
— Hash (64-bit hash) check of individual (unicast) addresses
— Hash (64-bit hash) check of group (multicast) addresses
— Promiscuous mode
Independent DMA engine with multiple channels allowing transmit data, transmit descriptor,
receive data, and receive descriptor accesses to provide high performance
Independent RISC-based controller that provides the following functions in the FEC:
— Initialization (those internal registers not initialized by the user or hardware)
— High level control of the DMA channels (initiating DMA transfers)
— Interpreting buffer descriptors
— Address recognition for receive frames
— Random number generation for transmit collision backoff timer
The Message Information Block (MIB) in FEC maintains counters for a variety of network events
and statistics. The counters supported are the RMON (RFC 1757) Ethernet Statistics group and
some of the IEEE 802.3 counters.
2.3.14
General Purpose I/O Module (GPIO)
The general-purpose input/output (GPIO) module provides dedicated general-purpose pins that can be
configured as either inputs or outputs. When it is configured as an output, you can write to an internal
register to control the state driven on the output pin. When configured as an input, you can detect the state
of the input by reading the state of an internal register. The GPIO includes all of the general purpose
input/output logic necessary to drive a specific data to the pad and control the direction of the pad using
registers in the GPIO module. The ARM926 is able to sample the status of the corresponding pads by
reading the appropriate status register. The GPIO supports up to 32 interrupts and has the ability to identify
interrupt edges as well as generate three active high interrupts.
2.3.15
General Purpose Timer (GPT)
The i.MX27/MX27L processors contains six identical 32-bit General Purpose Timers (GPT) with
programmable prescalers and compare and capture registers. Each timer’s counter value can be captured
using an external event, and can be configured to trigger a capture event on the rising or/and falling edges
of an input pulse. Each GPT can also generate an event on the TOUT pin, and an interrupt when the timer
reaches a programmed value. Each GPT has an 11-bit prescaler that provides a programmable clock
frequency derived from multiple clock sources, including ipg_clk_32k, ipg_clk_perclk, ipg_clk_perclk/4,
and external clock from the TIN pin. The counter has two operation modes: free-run and restart mode. The
GPT can work in low-power mode.
