TT = TTL compatible, B = Bi-directional, C = CMOS compatible, OD = Open Drain, I = Input, O = Output,
Z = high impedance

REAL TIME INTERRUPT: A low level on the RTI output indi-
cates the RIC2A's real time (packet specific) interrupt logic re-
quires CPU attention. The interrupt is cleared by reading the
Real Time Interrupt Status register. All interrupt sources may be
masked.
CDEC

COUNTER DECREMENT: A rising edge on the CDEC input
strobe decrements all of the RIC2A's Port Event Counters by
one. This input is internally synchronized and if necessary the
operation of the signal is delayed if there is a simultaneous in-
ternally generated counting operation.

WRITE STROBE: Strobe from the CPU used to write an internal
register defined by the RA0 - RA4 inputs.

READ STROBE: Strobe from the CPU used to read an internal
register defined by the RA0 - RA4 inputs.
MLOAD
92
TT
I
DEVICE RESET AND MODE LOAD: When this input cycles
back up from low to high, all of the RIC2A's state machines,
counters and network ports are reset and held inactive. On the
rising edge of MLOAD the logic levels present on the D0 - 7 pins
and RA0 - RA4 inputs are latched into the RIC2A's configuration
registers. The rising edge of MLOAD also signals the beginning
of the display test operation. The clock signal must be present
on the CLKIN pin during MLOAD assertion and de-assertion.
