Introduction
This section describes the mask options and the two mask option
registers. The mask options are hardwired connections specified at the
same time as the ROM code, which allow the user to customize the
MCU. The options control the enable or disable of the following
functions:
• Resets caused by the LVI module
• Power to the LVI module
• Stop mode recovery time (32 CGMXCLK cycles or 4096
CGMXCLK cycles)
• ROM security¹
• STOP instruction
• Computer operating properly (COP) module enable
• EEPROM security
1-morrom

1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
copying the ROM data difficult for unauthorized users
