I/O PORTS (Cont’d)
4.1.1 Details of I/O Ports
When programmed as an input a pull-up resistor (if
available) can be switched active under program
control. When programmed as an output the I/O
port will operate either in the push-pull mode or the
open-drain mode according to the hardware fixed
configuration as specified below.
Port A. PA0-PA3 are available as push-pull when
outputs. PA4-PA7 are available as open-drain (no
push-pull programmability) capable of withstand-
ing 12V (no resistive pull-up in input mode). PA6-
PA7 has been specially designed for higher driving
capability and are able to sink 25mA with a maxi-
mum VOL of 1V.
Port B. All lines are configured as push-pull when
outputs.
Port C. PC0-PC3 are available as open-drain ca-
pable of withstanding a maximum VDD+0.3V.
PC4-PC7 are avail-able as open-drain capable of
withstanding 12V (no resistive pull-up in input
mode). Some lines are also used as I/O buffers for
signals coming from the on-chip SPI.
In this case the final signal on the output pin is
equivalent to a wired AND with the programmed
data output.
If the user needs to use the serial peripheral, the I/
O line should be set in output mode while the
open-drain configuration is hardware fixed; the
corresponding data bit must set to one. If the
latched
interrupt
functions
are
used
(IRIN,
PWRIN) then the corresponding pins should be
set to input mode.
On ST638x the I/O pins with double or special
functions are:
– PC0/SCL (connected to the SPI clock signal)
– PC1/SDA (connected to the SPI data signal)
– PC3/SEN (connected to the SPI enable signal)
– PC4/PWRIN (connected to the PWRIN interrupt
latch)
– PC6/IRIN (connected to the IRIN interrupt latch)
All the Port A,B and C I/O lines have Schmitt-trig-
ger input configuration with a typical hysteresis of
1V.
