Hi, Aravind,

Regarding your question, it is dependent on which structure instance pointer in *.h is defined, if the SYSCON structure instance pointer is defined, you use the one:SYSCON->SYSAHBCLKCTRL |= GPIO;, if the LPC_SYSCON structure instance pointer is defined, you use the one:LPC_SYSCON->SYSAHBCLKCTRL |= GPIO;,

If you still have question about the topic, pls tell us the part number and the SDK package version.
