Chapter 17: LPC43xx/LPC43Sxx System Control Unit (SCU)/ IO
17.4 Register description
The system control unit contains the registers to configure the pin function of multiplexed
digital pins, the EMC clock delays, and the GPIO pin interrupts.
Remark:
The boot loader configures the pins involved in the boot process (see
) when the part starts up. The reset values given in
for the pin
configuration registers and EMC delay registers do not take into account the changes
performed by the boot loader.
