Just looking at this, it is not clear what these true/false mean. Maybe add some #defines

#define TC6_READ true
#define TC6_WRITE false
#define TC6_PROTECTED true
#define TC6_UNPROTECTED false

People don't always agree, but i found STATUS0_RESETC easier to see
you have the correct bit for the register you just read.
