6 IMPLEMENTATION DESCRIPTION
6.1 Bus Transceivers
Bus Transceivers have been used on the daughterboard to minimize the loading
presented to the motherboard microprocessor. Two 74HCT244's buffer all eight
upper address bits, the microprocessor control signals, and the external clock and
framing pulse inputs. A single 74HCT245 provides the bi-directional buffering of the
multiplexed address/data bus. All motherboard signals from the 96-pin DIN
connector have been tied through SIPs to insure proper standalone operation. The
standard techniques outlined in the EVMB datasheet for implementing the decoding
and buffering has been followed.
6.2 Decode Logic
The decode logic provides the address mapping of all internal registers of both
T1XC's as well as providing generation of the required RDB and WRB signals.
Again the implementation of the decode logic has followed the techniques outlined
in the EVMB datasheet. T1XC #1 (EAST) is mapped starting at address C000H and
T1XC #2 (WEST) is mapped starting at address C100H. Two unused chip selects,
active for address ranges C200-C2FFH and C300-C3FFH, are available for use on
the prototype section. The full register map is given below:
