MCS:
MCS bit (clock selection register) (PLL clock mode is selected when MCS = 0)
SCS:
SCS bit (clock selection register) (sub-clock mode is selected when SCS = 0)
STP:
STP bit (low power consumption mode register) (sleep mode is selected when SLP = 0)
SLP:
SLP bit (low power consumption mode register) (sleep mode is selected when SLP = 0)
TMD:
TMD bit (low power consumption mode register) (watch mode is selected when TMD = 0)
MCM:
MCM bit (clock selection register) (PLL clock is in use when MCM = 0)
SCM:
SCM bit (clock selection register) (sub-clock is in use when SCM = 0)
SCD:
Sub-clock oscillation stopped (sub-clock oscillation is stopped when SCD = 1)
MCD:
Main clock oscillation stopped (main clock oscillation is stopped when MCD = 1)
PCD:
PLL clock oscillation stopped (PLL clock oscillation is stopped when PCD = 1)
