CONFIGURATION
Tables 2 to 6 show the hardwired configuration for the different I/Os of the PCA5010.
Table 2
Port 0 configuration; notes 1 and 2
Notes
1.
Option 1S means port configuration option 1 with post-reset state set to HIGH; option 1R means post-reset state will
be LOW.
‘hys’ means input stage with hysteresis.
