The MCU reset signals are only valid during emulation started with clicking the GO or STEP-
type button. If these signals are enabled on the user system in command input wait state, they
are not sent to the MCU.
The DMAC operates even when the emulator is used. When a data transfer request is
generated, the DMAC executes DMA transfer.
During execution of the user program, memory is accessed by the following two methods, as
shown in table 3.2.
Method
H-UDI read/write
Short break
The method for accessing memory during execution of the user program is specified by using
the [Configuration] dialog box.
Method
H-UDI read/write
TIMEOUT error will occur. If the _BREQ or _WAIT signal is fixed to low during break,
a TIMEOUT error will occur at memory access.
Condition
Reading of one longword for the
internal RAM
Writing of one longword for the
internal RAM
Description
The stopping time of the user program is short because memory is
accessed by the dedicated bus master.
This function is not available in this emulator. (Do not set)
Stopping Time
Reading: Maximum three bus clock
cycles (Bφ)
Writing: Maximum two bus clock
cycles (Bφ)
