If illegal instructions are executed by STEP-type commands, the emulator cannot go to the
next program counter.
Display and modification
When [End] is set in the [UBC Mode] list box of the [Configuration] dialog box, do not
change values of the User Break Controller because it is used by the emulator.
For each watchdog timer register, there are two registers to be separately used for write and
read operations.
The watchdog timer operates only when the user program is executed. Do not change the
value of the frequency change register in the [IO] window or [Memory] window.
The internal I/O registers can be accessed from the [IO] window. However, note the
following when accessing the SDMR register of the bus-state controller. Before accessing
the SDMR register, specify addresses to be accessed in the I/O-register definition file
(SH7750.IO) and then activate the HEW. After the I/O-register definition file is created,
the MPU’s specification may be changed. If each I/O register in the I/O-register definition
file differs from addresses described in the hardware manual, change the I/O-register
definition file according to the description in the hardware manual. The I/O-register
definition file can be customized depending on its format. Note that, however, the E10A
emulator does not support the bit-field function.
Verify
In the [IO] window, the verify function of the input value is disabled.
SDMR registers in areas 2 and 3, respectively.
When the SH7750S is used, the IPRD register is not displayed in the [IO] window. To get
it to display, edit the I/O-register definition file (SH7750.IO) as follows and start the
HEW:
In SH7750.IO, locate ‘IPRC = 0xFFD0000C W A’. Under this, add ‘IPRD =
0xFFD00010 W A’ and save the file.
