6. Frame Table
The FrameTable of the Tiamis-800 includes total of 96 frames. Each of these frames is
executed by the transceiver in sequential order starting from ‘Frame0’.
The number of frames that the transceiver will execute from its FrameTable is
determined by the
NumberOfFrames settings. This parameter is user-programmable. Its
valid range is from 2 to 96. If the NumberOfFrames is set to a value lower than 96, then
the remainder of the frames in the transceiver’s FrameTable will be ignored.
Additionally, the transceiver starts its FrameTable by running a SystemSlot. The duration
of the SystemSlot is never less than ~700 usec and determined by the
SystemSlotBytes
settings. During the SystemSlot the transceiver checks its command buffer for valid
commands, executes the first valid command in the queue, and runs some housekeeping
routines. The duration of the SystemSlot is made adjustable via
SystemSlotBytes settings
so the FrameTable duration can be adjusted to aparticular application needs.
The content of each frame determines the transceiver’s functionality during this frame.
As shown on Figure 6-1, each frame in the FrameTable has four sections:
