STATUS – Oscillator Status Register
XOSCCTRL – XOSC Control Register
• Bit 7:5 – Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bit 4 – PLLRDY: PLL Ready
This flag is set when the PLL has locked on the selected frequency and is ready to be used as
the system clock source.
• Bit 3 – XOSCRDY: External Clock Source Ready
This flag is set when the external clock source is stable and is ready to be used as the system
clock source.
• Bit 2 – RC32KRDY: 32.768kHz Internal Oscillator Ready
This flag is set when the 32.768kHz internal oscillator is stable and is ready to be used as the
system clock source.
• Bit 1 – RC32MRDY: 32MHz Internal Oscillator Ready
This flag is set when the 32MHz internal oscillator is stable and is ready to be used as the sys-
tem clock source.
• Bit 0 – RC2MRDY: 2MHz Internal Oscillator Ready
This flag is set when the 2MHz internal oscillator is stable and is ready to be used as the system
clock source.
• Bit 7:6 – FRQRANGE[1:0]: 0.4 - 16MHz Crystal Oscillator Frequency Range Select
These bits select the frequency range for the connected crystal oscillator according to
