3.31. General Circuit Interface
The Dual ProSLIC devices also contain an alternate
communication interface to the SPI and PCM control
and data interface. The general circuit interface (GCI) is
used for the transmission and reception of both control
and data information onto a GCI bus. The PCM and GCI
interfaces are both four-wire interfaces and share the
same pins. The SPI control interface is not used as a
communication interface in the GCI mode but rather as
hard-wired
channel
selector
pins.
The
selection
between PCM and GCI modes is performed out of reset
to select the communication mode and how the pins are
used in each mode.
If GCI mode is selected, the following pins must be tied
to the correct state to select one of eight subframe
timeslots in the GCI frame (described below). These
pins must remain in this state while the Dual ProSLIC is
operating. Selecting a particular subframe causes that
individual Dual ProSLIC device to transmit and receive
on the appropriate subframe in the GCI frame, which is
initiated by an FSYNC pulse. No further register settings
are needed to select which subframe a device uses,
and the subframe for a particular device cannot be
changed while in operation.
In GCI mode, the PCLK input requires either a
2.048 MHz or a 4.096 MHz clock signal, and the
FSYNC input requires an 8 kHz frame sync signal. The
overall unit of data used to communicate on the GCI
highway is a frame 125 s in length. Each frame is
initiated by a pulse on the FSYNC pin whose rising
edge signifies the beginning of the next frame. In 2x
PCLK mode, the user sees twice as many PCLK cycles
during each 125 s frame versus 1x PCLK mode. Each
frame consists of eight fixed timeslot subframes that are
assigned by the subframe select pins as described
above (SDI, SDO, and CS). Within each subframe are
four channels (bytes) of data including two voice data
channels, B1 and B2, one Monitor channel, M, used for
initialization and setup of the device, and one Signaling
and Control channel, SC, used for communicating the
status of the device and initiating commands. Within the
SC channel are six Command/Indicate (C/I) bits and two
