3.1
Exception handling is performed in the H8/38024 Group, H8/38024S Group, H8/38024F-ZTAT
Group, and H8/38124 Group when a reset or interrupt occurs. Table 3.1 shows the priorities of
these two types of exception handling.
Table 3.1
Priority
High

3.2.1
A reset is the highest-priority exception. The internal state of the CPU and the registers of the on-
chip peripheral modules are initialized.
3.2.2
As soon as the RES pin goes low, all processing is stopped and the chip enters the reset state.
To make sure the chip is reset properly, observe the following precautions.
• At power on: Hold the RES pin low until the clock pulse generator output stabilizes.
• Resetting during operation: Hold the RES pin low for at least 10 system clock cycles.
Reset exception handling takes place as follows.
• The CPU internal state and the registers of on-chip peripheral modules are initialized, with the
• The PC is loaded from the reset exception handling vector address (H'0000 to H'0001), after
I bit of the condition code register (CCR) set to 1.
which the program starts executing from the address indicated in PC.
