ERRATA
An 80C186EB/80L186EB with a STEPID value of
0001H has the following known errata. A device with
a STEPID of 0001H can be visually identified by the
presence
of an
‘‘A’’
alpha character next to the
FPO number. The FPO number location is shown in
Figures 4, 5 and 6.
1. A19/ONCE is not latched by the rising edge of
RESIN. A19/ONCE must remain active (LOW) at
all times to remain in the ONCE Mode. Removing
A19/ONCE after RESIN is high will return all out-

2. During interrupt acknowledge (INTA) bus cycles,
the bus controller will ignore the state of the
READY pin if the previous bus cycle ignored the
state of the READY pin. This errata can only oc-
cur if the Chip-Select Unit is being used. All active
chip-selects must be programmed to use READY
(RDY bit must be programmed to a 1) if wait-
states are required for INTA bus cycles.
3. CLKOUT will transition off the
rising
edge of
CLKIN rather than the falling edge of CLKIN. This
does not affect any bus timings other than T
CD
.
4. RESIN has a hysterisis of only 130 mV. It is rec-
ommended that RESIN be driven by a Schmitt
triggered device to avoid processor lockup during
reset using an RC circuit.
5. SINT1 will only go active for one clock period
when a receive or transmit interrupt is pending
(i.e., it does not remain active until the S1STS
register is read). If SINT1 is to be connected to
any of the processor interrupt lines (INT0–INT4),
then it must be latched by user logic.
An 80C186EB/80L186EB with a STEPID value of
0001H or 0002H has the following known errata. A
device with a STEPID of 0002H can be visually iden-
tified by noting the presence of a ‘‘B’’, ‘‘C’’, ‘‘D’’, or
‘‘E’’ alpha character next to the FPO number. The
FPO number location is shown in Figures 4, 5 and 6.
1. An internal condition with the interrupt controller
can cause no acknowledge cycle on the INTA1
line in response to INT1. This errata only occurs
when Interrupt 1 is configured in cascade mode
and a higher priority interrupt exists. This errata
will not occur consistantly, it is dependent on in-
terrupt timing.
