CMOS Z8® MCUs with ASCI UART
er operates in STOP mode, and cannot be enabled, by any
means, to operate in STOP mode.
Auto Latch Mode. Selecting the DISABLE AUTOLATCH-
ES option disables the autolatches on the Port pins. These
pins will float rather than be pulled to a valid CMOS level
when they are inputs and not connected to an external sig-
nal. Selecting the ENABLE AUTOLATCHES option enables
the autolatches on the Port pins and pulls the pins to a valid
CMOS level when they are not connected to an external sig-
nal.
Port 0 Pull-Ups. Selecting DISABLE PULL-UPS disables
the input pull-up circuitry on all Port 0 pins. Selecting EN-
ABLE PULL-UPS enables the input pull-up circuitry on all
Port 0 pins. This option bit does not affect any of the other
port pins on the part.
Port 1 Pull-Ups. Selecting DISABLE PULL-UPS disables
the input pull-up circuitry on all Port 1 pins. Selecting EN-
ABLE PULL-UPS enables the input pull-up circuitry on all
Port 1 pins. This option bit does not affect any of the other
port pins on the part.
Port 2 Pull-Ups. Selecting DISABLE PULL-UPS disables
the input pull-up circuitry on all Port 2 pins. Selecting EN-
ABLE PULL-UPS enables the input pull-up circuitry on all
Port 2 pins. This option bit does not affect any of the other
port pins on the part.
