This register determines the active page viewed through
MC68HC912DT128A windows.
CALL and RTC instructions have a special single wire mechanism to
read and write this register without using an address bus.
Additional mapping and external resource controls are available. To use
external resources the part must be operated in one of the expanded
modes.
Normal modes: write once; Special modes: write anytime. Read
anytime.
ROMTST — FLASH EEPROM Test mode
In normal modes, this bit is forced to zero.
