Product data sheet
6.16.4.1 Functional description
6.16.4.2 Pin description
Each reset output is defined as a combination of reset input sources including the external
reset input pins and internal power-on reset, see
this table form a sort of cascade to provide the multiple levels of impact that a reset may
have. The combined input sources are logically OR-ed together so that activating any of
the listed reset sources causes the output to go active.
Table 30.
The RGU module in the LPC2939 has the following pins.
