Hi all,

Please let me know what's the max frequency achieved by toggling GPIO pin on LPC18xx running @ 180MHz or less.


I do not have a board to run sample code to test this (board got bricked) please share details or give me pointers in trm where I can find the details.


Toggle not by PWM, just be set or clearing a gpio.


Thanks in advance
