9.2 Introduction
This section describes the configuration registers, CONFIG1 and
CONFIG2. The configuration registers control these options:
• Stop mode recovery time, 32 CGMXCLK cycles or 4096
CGMXCLK cycles
• Computer operating properly (COP) timeout period, 2¹⁸–2⁴ or
2¹³â€“2⁴ CGMXCLK cycles
• STOP instruction
• Computer operating properly (COP) module
• Low-voltage inhibit (LVI) module control and voltage trip point
selection
• Enable/disable the oscillator (OSC) during stop mode
• Serial communications interface (SCI) clock source selection
• External clock/crystal source control
• Enable/disable for the FLASH charge-pump regulator
