Table 19.5 shows the scope of the host interface pin shutdown.
Table 19.5 Scope of Host Interface Pin Shutdown
Legend:
O: Pin that is shutdown by the shutdown function
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)
2. LPC hardware reset (reset by LRESET pin input)
3. LPC software reset (reset by LRSTB)
4. LPC hardware shutdown
5. LPC software shutdown

Pin that is shutdown only when the LPC function is selected by register setting
Pin that is not shutdown
All register bits, including bits LPC3E to LPC1E, are initialized.
LRSTB, SDWNE, and SDWNB bits are cleared to 0.
SDWNE and SDWNB bits are cleared to 0.
SDWNB bit is cleared to 0.
