Signaling freezing
Ability to pass the T1 F-bit position through the elastic stores in the 2.048MHz backplane mode
User-selectable synthesized clock output
HDLC Controllers
One HDLC controller engine for each T1/E1 port
Independent 64-byte Rx and Tx buffers with interrupt support
Access FDL, Sa, or single DS0 channel
Compatible with polled or interrupt driven environments
Test and Diagnostics
IEEE 1149.1 support
Per-channel programmable on-chip bit error-rate testing (BERT)
Pseudorandom patterns including QRSS
User-defined repetitive patterns
Daly pattern
Error insertion single and continuous
Total-bit and errored-bit counts
Payload error insertion
Error insertion in the payload portion of the T1 frame in the transmit path
Errors can be inserted over the entire frame or selected channels
Insertion options include continuous and absolute number with selectable insertion rates
F-bit corruption for line testing
Loopbacks (remote, local, analog, and per-channel loopback)
Microcontroller Parallel Port
8-bit parallel control port
Intel or Motorola nonmultiplexed support
Flexible status registers support polled, interrupt, or hybrid program environments
Software reset supported
Hardware reset pin
Software access to device ID and silicon revision
Slave Serial Peripheral Interface (SPI) Features
Software access to device ID and silicon revision
Three-wire synchronous serial data link operating in full-duplex slave mode up to 5Mbps
Glueless connection and fully compliant to Motorola popular communication processors such as MPC8260
and microcontrollers such as M68HC11
Software provision ability for active phase of the serial clock (i.e., rising edge vs. falling edge), bit ordering
of the serial data (most significant first vs. least significant bit first)
Flexible status registers support polled, interrupt, or hybrid program environments
