O:

∆:

×:
Pin that is not shutdown
In the LPC shutdown state, the LPC's internal state and some register bits are initialized. The order
of priority of LPC shutdown and reset states is as follows.
1. System reset (reset by STBY or RES pin input, or WDT0 overflow)
 All register bits, including bits LPC3E to LPC1E, are initialized.
2. LPC hardware reset (reset by LRESET pin input)
 LRSTB, SDWNE, and SDWNB bits are cleared to 0.
3. LPC software reset (reset by LRSTB)
 SDWNE and SDWNB bits are cleared to 0.
4. LPC hardware shutdown
 SDWNB bit is cleared to 0.
5. LPC software shutdown
