Notes:
Access to an area for writing to the internal ROM (H’D00000 to H’DFFFFF) is indicated as “I/O16”.
Access to the internal RAM area for use by the FCU (H’EF8000 to H’EF97FF) is indicated as “I/O16”.
Access to the firmware area for use by the FCU (H’C00000 to H’C01FFF) is indicated as “-”.
Access to an internal ROM area to which emulation memory has been assigned is indicated as “-”.

displayed.
0 indicates that the emulator has taken over the MCU bus while the user program was running. The
emulator takes over the MCU bus when access to memory is attempted by a debugger operation.
Note: Execution of the user program is temporarily stopped during such access to memory.
Whether the cycle was a user-bus release cycle (i.e. the external bus of the target MCU had been released
and a low-level signal was being output).
0: The external bus had been released.
1: The external bus had not been released.
Monitoring of user IRQ.
0: An interrupt has been detected.
1: No interrupt has been detected.
Whether the write-data buffer function was used and a low-level signal was being output.
0: The write-data buffer function was used.
1: The write-data buffer function was not used.
