| description: | |
| This flag disables the automatic reset, which allows the implementation |
| of for instance an external state retention of the port expander. If |
| this flag is set it must be ensured that for an actually uninitialized |
| port expander the manual reset is triggered via the exposed reset |
| function, specific to the PCAL64XXA. |
