Reading Input1 (SPI Instruction: RD_INP1)
:
Reading Input2 (SPI Instruction: RD_INP2):
The input pins IN1..IN5 and IN8...IN15 can be used as input port expander by reading the status of
the input pins using the SPI-commands RD_INP1/2. If the μsec-bus-interface is enabled (BMUX=0) the
pull-up current sources at the input IN1..5 and IN9..15 are disabled. If BMUX=1 the pullup current
sources at these pins are enabled. The pull-up/pull-down current sources of the other input pins are
not effected by the bit BMUX.
On executing the read instruction on RD_INP1/2, the present status (not latched) of the input pins INx is
read back (exception: bit IN8 represents the
inverted
status of input pin IN8).
