User manual
Depending on the system clock frequency, access to the flash memory can be configured
with various access times by writing to the FLASHCFG register at address 0x4003 C010.
Remark: Improper setting of this register may result in incorrect operation of the
LPC111x/LPC11Cxx flash memory.

Flash memory access time. FLASHTIM +1 is equal to the
number of system clocks used for flash access.
1 system clock flash access time (for system clock
frequencies of up to 20 MHz).
2 system clocks flash access time (for system clock
frequencies of up to 40 MHz).
3 system clocks flash access time (for system clock
frequencies of up to 50 MHz).
