9.1 Device-specific information
The Low Voltage Reset feature uses the low voltage reset signal from the VREG module as an input to the
CRG module. When the regulator output voltage supply to the internal chip logic falls below a specified
threshold the LVR signal from the VREG module causes the CRG module to generate a reset.
NOTE: If the voltage regulator is shut down by connecting VDDR to ground then the LVRF flag in the
CRG Flags Register (CRGFLG) is undefined.
9.1.1 XCLKS
The XCLKS input signal is active low (see 2.3.8 PE7 / NOACC / XCLKS — Port E I/O Pin 7).
Section 10 Oscillator (OSC) Block Description
Consult the OSC Block User Guide for information about the Oscillator module.
Section 11 Timer (TIM) Block Description
Consult the TIM_16B8C Block User Guide for information about the Timer module.
Section 12 Analog to Digital Converter (ATD) Block
Description
12.1 Device-specific information
12.1.1 VRL (voltage reference low)
In the 48 and 52 pin package versions, the VRL pad is bonded internally to the VSSA pin.
Consult the ATD_10B8C Block User Guide for further information about the A/D Converter module.
