Section 5 Differences between the MCU (H8/38602RF) and the Emulator
Table 5.3 Registers Not Initialized
MCU Name
H8/38602RF
Register Not Initialized
SYSCR1, SYSCR2, IEGR, IENR1, IENR2, OSCCR, IRR1, IRR2, CKSTPR1,
CKSTPR2
20. Step Execution of the SLEEP Instruction
When the interrupt mask bit (I) in the condition code register (CCR) is 1, do not perform step
execution of the SLEEP instruction. If the step execution is performed and not finished
correctly, restart the emulator.
21. Use of the internal oscillator circuit is available in the H8/38602RF. However, a resonator or
an oscillator must be connected to OSC1 and OSC2 pins when the emulator is connected.
22. Processing at Emulator Activation
When the emulator is activated, the watchdog timer is not active; the operation of the emulator
differs from that of the MCU.
23. Hardware Break Functions
• In the H8/38602RF E8a emulator, conditions of Break Condition 1,2 can be set. Table 5.4
lists the items that can be specified.
Table 5.4 Hardware Break Condition Specification Items
Items
Address bus condition
Data bus condition
Read or write condition
Description
Breaks when the MCU address bus value matches the
specified value.
Breaks when the MCU data bus value matches the specified
value. High or low byte or word can be specified as the
access data size.
Breaks in the read or write cycle.
