Lead Descriptions
Microprocessor Interface Select: These leads select the Host
Processor interface mode:
of the MPINTR lead. If MPINTLEVEL is low, the interrupt on the
MPINTR lead is active low, if MPINTLEVEL is high, the interrupt
on the MPINTR lead is active high.
This lead is evaluated in all modes (MPMODE[1:0] = ‘00’, ‘01’,
‘10’ and ‘11’).
polarity of the MPACK lead. If MPACKLEVEL is low, an acknowl-
edge is indicated by a falling edge of MPACK, if MPACKLEVEL
is high, an acknowledge is indicated by a rising edge of MPACK.
This lead is only evaluated in Generic Intel Mode (MPMODE[1:0]
= ‘00’) and Generic Motorola Mode (MPMODE[1:0] = ‘01’).
This lead must be tied to VSS when MPMODE[1:0] = ‘10’ or ‘11’.
