Chapter 7: LPC13xx I/O configuration
The pin functions selectable in each IOCON register are listed in order (function 0/function
1/function 2/...) in the description column in Table 95
.
Remark: The IOCON registers are listed in order of their memory locations in Table 95
which correspond to the order of their physical pin numbers in the LQFP48 package
starting at the upper left corner with pin 1 (PIO2_6). See Table 96
for a listing of IOCON
registers ordered by port number.
