NSTOP
Not STOP peripheral clock
NSTOP = 0, stops the peripheral clock while the core is in SLEEP mode
NSTOP = 1, enables the peripheral clock while the core is in SLEEP mode
CCS
Core Clock Select
CCS = 1, the internal RC-oscillator 1 generates SYSCL
CCS = 0, the 4-MHz crystal oscillator, the 32-kHz crystal oscillator, an external
clock source or the RC-oscillator 2 with the external resistor at OSC1
generates SYSCL dependent on the setting of OS0 and OS1 in the
system configuration register
