Note: This register is reset to 00h on init or reset. The BIOS resides in page 000.
The ZT 5515 provides several system registers to control and monitor a variety of functions.
Normally, only the system BIOS uses these registers, but they are documented here for application
use as needed. Take care when modifying the contents of these registers, as the system BIOS may
be relying on the state of some bits.
