6.2 Introduction
This section describes the configuration registers, CONFIG1 and
CONFIG2. The configuration registers enable or disable these options:
• Low-voltage inhibit (LVI) in stop mode
• LVI reset
• LVI module power
• Stop mode recovery time (32 CGMXCLK cycles or 4096
CGMXCLK cycles)
• COP timeout period (2¹⁸ – 2⁴ or 2¹³ – 2⁴ CGMXCLK cycles)
• STOP instruction
• Computer operating properly module (COP)
• EEPROM reference clock source (CPU bus clock or CGMXCLK)
