37
of Timer3 can be found in locations 0Fh (high byte), and 0Eh
(low byte) of HWindow 1.
1.15 Input/Output Pullup/Pulldown Currents
Leakage currents may not meet the industry standard
80C196KD specs due to differently sized weak pullups/
pulldowns, during Quasi-Bidirectional and reset/powerdown
modes. Refer to specs for I
LI1
and I
LI2
.
1.16 Power-down exit
Pin 37 will not be used to exit power-down mode. Since a digital
clock is supplied, no connection between this V
pp
pin and the
power-down circuitry exists.
1.17 Test Mode Entry
Test mode entry will be via four pins: WR, RD, ALE and HLDA
instead of PWM0.
1.18 Power-on Reset
The UT80C196KD will not guarantee the 16-state "pulse
stretching" function of a Reset_n pulse applied at power-up. The
user must hold Reset_n low until the power and clocks stabilize
plus 16-state times, or provide a high to low transition after the
power and clocks have stabilized.
1.19 Pullup/Pulldown states
The INST pin will be driven to a weak low during Reset. The
ALE signal will be driven to a weak high during Bus Hold.
1.20 Modifying the INT_PEND registers
Two operand rd-modify-wr instructions should be used to
modify the INT_PEND registers. Three operand rd-modify-wr
instructions may lose an incoming interrupt.
1.21 Serial Port Synchronous Mode
The last clock rising edge to output float time (T
XHQZ
) is made
consistent with the output data hold (T
XHQX
) time of 2 T
OSC
+/-50nsec. This is longer than the industry standard of 1 T
OSC
max.
1.22 Industry Standard Register Indirect with Auto Incre-
ment
The industry standard 80C196KD increments the auto-incre-
mented register after determining the external address instead
of at the end of the instruction completion. The UT80C196KD
performs the auto-increment function at the end of the instruc-
tion processing. Please reference the example below that
shows the processing difference between the UT80C196KD
and the industry standard 80C196KD:
ST R0, [R0]+
assume R0 holds the value 1000h before the instruction is exe-
cuted.
1.23 AC Timing Differences
There are some AC timing differences between the
UT80C196KD and the industry standard 80C196KD. Most
changes resulted in loosened timing specifications. However,
the t
RHDZ
and t
RXDX
timing specifications were tightened by
5ns. If you have been designing to the industry standard
80C196KD timing specifications, it is important to recognize
these two shortened timing specifications.

1.24 T2UP-DN Input Signal
Port 2.6 has an alternate function of T2UP-DN enabled by
IOC2.1. The industry standard device appears to allow writes
into Port 2.6 to directly affect the pin state when in the T2UP-
DN mode. (This would allow software control of the T2 direc-
tion, but requires ensuring a one (QBD pullup) is written to
Port 2.6 if the pin is driven externally). The UT80C196KD
device is designed to disable the Port 2.6 output when T2UP-
DN is enabled. This protects the P2.6/T2UP-DN pin from con-
tention with an externally driven signal, independent of the
value written into Port 2.
1.25 NEG 8000h Instruction Operation
The UT80CRH196KD and the industry standard 80C196KD
set the N-Flag differently when executing the NEG 8000h
instruction. NEG represents the MCS-96 opcode to negate a
defined operand (8000h). When the UT80CRH196KD exe-
cutes the NEG 8000h instruction, the result becomes 8000h
with both the N-Flag and the V-Flag set. The industry stan-
dard 80C196KD, however, executes the NEG 8000h instruc-
tion with a result of 8000h and only the V-Flag set.
