Figure 14-1. I/O configuration - Totem-pole
Figure 14-2. I/O configuration - Totem-pole with pull-down (on input)
Figure 14-3. I/O configuration - Totem-pole with pull-up (on input)
The bus-keeper’s weak output produces the same logical level as the last output level. It acts as
a pull-up if the last level was ‘1’, and pull-down if the last level was ‘0’.
