MCU
The interrupt processing starts
after instruction 1) is executed, in
the following example:
1) MOV.B R0L,@ECR
2) EEPMOV.B
No UDF interrupt processing is
performed between the RTE
instruction at the end of the EWE
interrupt processing and the
instruction following the RTE
instruction.
MCU
Set to 1 at cold reset.
E6000 Emulator
If a break is specified or single-step
execution is performed for the example
instructions on the left, the EWE
interrupt timing in the E6000 emulator
differs from that in the MCU.
If a break is specified or single-step
execution is performed for the RTE
instruction described on the left, a UDF
interrupt will occur.
E6000 Emulator
The CRES bit is always set to 1 when
the user system interface cable is not
connected. When the user system
interface cable is connected, high or
low of the CRES bit is determined by
the User Vcc Threshold power supply
level of the user power supply voltage
monitoring function of the emulator.
