Bit-3	PSA	Prescaler Assignment Bit 0 = Prescaler assigned to Timer0. 1 = Prescaler assigned to WDT.
Bit-4	T0SE	Timer0 Source Edge Select Bit 0 = increment on low-to-high transition on T0CKI pin. 1 = increment on high-to-low transition on T0CKI pin.
Bit-5	T0CS	Timer0 Clock Source Select Bit 0 = Transition on T0CKI pin. 1 = Transition on internal instruction cycle clock.
Bit-6	/GPPU	Enable Weak Pull-ups Bit(GP0, GP1, GP3) 0 = Enabled 1 = Disabled
Bit-7	/GPWU	Enable Wake-up on Pin Change Bit(GP0, GP1, GP3) 0 = Enabled 1 = Disabled
