5.2 Introduction
This section describes the configuration registers, CONFIG1 and
CONFIG2. The configuration registers enable or disable these options:
• Computer operating properly module (COP)
• COP timeout period (2¹⁸ – 2⁴ or 2¹³ – 2⁴ ICLK cycles)
• Low-voltage inhibit (LVI) module power
• LVI module reset
• LVI module in stop mode
• LVI module voltage trip point selection
• STOP instruction
• Stop mode recovery time (32 ICLK cycles or 4096 ICLK cycles)
• Oscillator during stop mode
• LCD frontplanes FP19–FP26 on port C
