Function
SCON
System Controller (SCON)
Tsi148 has VMEbus System Controller (SCON) functionality. The SCONEN_ and
SCONDIS_ signals are used to control the SCON function. If the SCONEN_ signal is low
and the SCONDIS_ signal is high at the rising edge of PUSRTI_, the SCON function is
enabled. If the SCONEN_ signal is high and the SCONDIS_ signal is low at the rising edge of
PURSTI_, the SCON function is disabled. If the SCONEN_ signal and the SCONDIS_ signal
are both high at the rising edge of PUSRTI_, the Auto System Controller feature is used.
The Auto System Controller feature uses the BG3IN_ signal to enable a board to determine if
it is in VMEbus slot 1. If the board is in VMEbus slot 1, the BG3IN_ signal is low and the
SCON function is enabled. If the board is not in VMEbus slot 1, the BG3IN_ signal is high
and the SCON function is disabled.
