for T3* boards most register symbols are defined in hardware/teensy/avr/cores/teensy3/kinetis.hOn the Teensy 3.6 the register CMT_PPS has the address 0x4006200A according to the datasheet. How can I access the CMT_PPS register using this address?
#define CMT_PPS (*(volatile uint8_t *)0x4006200A) // CMT Primary Prescaler Register
