3.2.2
High-sink capability
Most of the I/Os with high sink capability are in Ports C and D. The Access line family
(STM8S10xx) has a greater number of high sink pins, which are also spread out in the other
ports. See Table 19.
3.2.3
External interrupts
In general only five ports (PA to PE) have external interrupts capability. However in the
STM8S903x sub-family external interrupt capability with a dedicated interrupt vector for port
PF is added.
