Several boot modes are available depending on the values of the OTP bits BOOT_SRC. If
the OTP memory is not programmed or the BOOT_SRC bits are all zero, the boot mode is
determined by the states of the boot pins P2_8, P1_2, and P1_1.

interface using pins P3_3 to P3_8.
Boot from external static memory (such as NOR
flash) using CS0 and an 8-bit data bus.
Boot from external static memory (such as NOR
flash) using CS0 and a 16-bit data bus.
