Clocks
HOCO FLL Function	Enabled Disabled	Disabled	Setting this option to Enabled improves HOCO accuracy significantly by using the subclock, but incurs certain restrictions. The FLL function requires the subclock oscillator to be running and stabilized. When enabled and running the PLL or system clock from HOCO, the BSP will wait for both the Subclock Stabilization Time as well as the FLL Stabilization Time when setting up clocks at startup. When FLL is enabled Software Standby and Deep Software Standby modes are not available.
MOSC Drive Capability Auto Switching	Enabled Disabled	Disabled	When enabled, the drive capability auto switching function lowers the MOSC drive capability automatically after the MOSC starts and suppresses the EMI associated with the MOSC.
Main Oscillator Wait Time	35 cycles 67 cycles 131 cycles 259 cycles 547 cycles 1059 cycles 2147 cycles 4291 cycles 8163 cycles	8163 cycles	Number of cycles to wait for the main oscillator clock to stabilize.
Enable inline BSP IRQ functions	Enabled Disabled	Enabled	Using static inline functions will slightly increase code size, but will slightly decrease cycles taken in ISRs in return.
ID Code Mode	Unlocked (Ignore ID) Locked with All Erase support Locked	Unlocked (Ignore ID)	When set to 'Locked with All Erase support', the ID Code must be set in the debugger to read or write data to the MCU, but the All Erase command is still accepted regardless. When set to 'Locked', all erase/download/debug access is disabled unless the ID Code is provided.
ID Code (32 Hex Characters)	Value must be a 32 character long hex string	FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF	Set the ID Code for locking debug access. This setting is only used when the ID Code Mode is not set to Unlocked.
