9. Multi MONITOR
The ROM chip on the board is incorporated with the Multi monitor. The following cautions
should be observed when the board is connected to the Multi server as the host.
9.1. MONITOR WORK RAM
The monitor uses the SRAM area between the start address and 2000H as work RAM. In other
words, user programs are not allowed to use addresses FF00-0000H to FF00-1FFFH.
9.2. INTERRUPTS
When running on the Multi monitor, user programs cannot use interrupts at present. When the
internal I/O is used, interrupts cannot be used.
9.3. _INIT_SP SETTING
_INIT_SP (stack pointer initial value) is set to FF01-FFFCH (highest SRAM address) by the
monitor. (_INIT_SP can be changed in the Multi environment.)
9.4. REMOTE CONNECTION
Either serial or ISA bus connection can be selected for operation with the Multi server. To
switch from serial connection to ISA bus connection or vice versa, it is necessary to reset the
monitor (by pressing the reset switch on the rear panel) and run the Check RTE utility of RTE for
Windows.
