Section 3 Exception Handling
3.2
A reset has the highest exception priority.
There are three sources to generate a reset. Table 3.2 lists the reset sources.
Table 3.2
3.2.1
When a reset source is generated, all the processing in execution is terminated and this LSI enters
the reset state. The internal state of the CPU and the registers of the on-chip peripheral modules
are initialized by a reset.
To ensure that this LSI is reset, handle the RES pin as shown below.
• When power is supplied, or the system clock oscillator is stopped
• When the system clock oscillator is operating
After a reset source is generated, this LSI starts reset exception handling as follows.
1. The internal state of the CPU and the registers of the on-chip peripheral modules are
2. The reset exception handling vector address (H'0000 and H'0001) is read and transferred to the
The reset exception handling sequence by the RES pin is shown in figure 3.1.
