3.1 How to read this chapter
The system configuration registers apply to all LPC13xx parts with the following
exceptions:
USB clocking and power control
Since the USB block is available on the LPC1342 and LPC1343 only, the registers and
register bits listed in Table 4
are reserved for parts LPC1311 and LPC1313:
SSP1
The SSP1 block is available on the LPC1313FBD48/01 only. SSP1 related registers and
register bits are reserved for the following parts: LPC1311/13/42/43 and
LPC1311FHN33/01 and LPC1313FHN33/01.
BOD control
The number of programmable BOD levels for forced reset is different for the LPC1300 and
the LPC1300L series. See Table 5
. The BOD trip levels for the LPC1300 and LPC1300L
series are listed in the LPC1311/13/42/43 data sheet.
