Chapter 4: Configuring the Emulator
Configuring the Emulator Pod
To set the processor data bus width
• Answer "yes" to the "Data bus width 16 bits?" question to set 16-bit mode; answer
"no" to set 8-bit mode.
The data bus width setting only applies when operating the emulator out-of-circuit
(that is, not connected to the target system). When in circuit, the target system
BUSW pin overrides the answer to this configuration question.
When an 8-bit data bus width is specified, target memory is always accessed as
bytes, and the "Target memory access size?" configuration question is not asked.
To specify the target memory access size
• Answer the "Target memory access size?" question.
The target memory access size only applies when a 16-bit data bus width is selected
(either by the previous "Data bus width 16 bits?" configuration question when
out-of-circuit or by the BUSW pin when in-circuit).
When accessing target system memory locations, the access mode specifies the type
of microprocessor cycles that are used to read or write the value(s). For example,
when the access mode is byte and a target system location is modified to contain
the value 12345678H, byte instructions are used to write the byte values 12H, 34H,
56H, and 78H to target system memory.
Answer "bytes" if the emulator should make 8-bit accesses to target system
memory.
Answer "words" if the emulator should make 16-bit accesses to target system
memory.
