OSC3 (crystal/ceramic) oscillator circuit configurations

The OSC3 (crystal/ceramic) oscillator circuit provides some configuration items to support various crystal and
ceramic resonators. These configurations trade off current consumption for performance as shown below.
•  The lower oscillation inverter gain setting (CLGOSC3.OSC3INV[1:0] bits) decreases current consumption.
•  Using lower OSC3 external gate and drain capacitances decreases current consumption.
•  Using a resonator with lower C

L

value decreases current consumption.

However, these configurations may reduce the oscillation margin and increase the frequency error, therefore, be
sure to perform matching evaluation using the actual printed circuit board.

B.2 Other Power Saving Methods

Supply voltage detector configuration

Continuous operation mode (SVDCTL.SVDMD[1:0] bits = 0x0) always detects the power supply voltage,
therefore, it increases current consumption. Set the supply voltage detector to intermittent operation mode or
turn it on only when required.
