MK22FN512 register layout typedefs

Hi,

Recently i started digging more into files provided by NXP and i found out something i can't really explain. My question is how exactly uint8_t array of 252 elements gives 100 offset? Could u please clear that out? Thanks :smileyhappy:

Hi Brian

PIT_MCR is at address 0x40037000 and is 32 bits in size (and thus occupies 4 bytes)
Add 252 bytes to that and you get to the offset 256.

In the struct PIT_LDVAL will therefore be a 0x40037100 (0x40037000 + 4 + 252)
