Z86E33/733/E34/E43/743/E44
CMOS Z8 OTP Microcontrollers
Comparator Inputs. Port 3, P31, and P32, each have a
comparator front end. The comparator reference voltage
P33 is common to both comparators. In analog mode, P31
and P32 are the positive input of the comparators and P33
is the reference voltage of the comparators.
Auto Latch. The Auto Latch puts valid CMOS levels on all
CMOS inputs (except P33-P31) that are not externally
driven. Whether this level is 0 or 1, cannot be determined.
A valid CMOS level, rather than a floating node, reduces
excessive supply current flow in the input buffer. Auto
Latches are available on Port 0, Port 1, Port 2, and P30.
There are no Auto Latches on P31, P32, and P33.
Low EMI Emission. The
grammed to operate in a low EMI Emission Mode in the
PCON register. The oscillator and all I/O ports can be pro-
grammed as low EMI emission mode independently. Use
of this feature results in:

The pre-drivers slew rate reduced to 10 ns typical.
Low EMI output drivers have resistance of 200 Ohms
(typical).
Low EMI Oscillator.
Internal SCLK/TCLK= XTAL operation limited to a
maximum of 4 MHz - 250 ns cycle time, when Low EMI
Oscillator is selected.
Note for emulation only:
Do not set the emulator to emulate Port 1 in low EMI
mode. Port 1 must always be configured in Standard
Mode.
