CHAPTER 5 RESTRICTIONS
The IE-703204-G1-EM1 has the following restrictions.
5.1
Clock Generator
(1) Resonator to be connected
Oscillation by the resonator on the target system is not supported. Therefore, clock oscillation operation on
the target system cannot be emulated with the in-circuit emulator.
(2) Emulation of oscillation stabilization time after reset has been released
In the target device for emulation, oscillation stabilization time is inserted after reset has been released;
however, it is not inserted in the in-circuit emulator.
(3) Operation clock after reset
In the target device for emulation, the operation clock after reset is f
XX
/8; however, there may be a period in
which the clock is not initialized to f
XX
/8 with the in-circuit emulator (depending on the timing of reset release).
5.2
Timing of Setting/Releasing Standby Mode
The timing of setting/releasing the standby mode is different between the target device and the in-circuit emulator.
The difference is within 1 clock when standby mode is set, and 2 or 3 clocks when it is released.
5.3
DMA
The status of the DCHC0 to DCHC3 registers of the DMA function vary when read; however, these registers
cannot be displayed by the I/O register browser of the debugger.
5.4
Operation During Break
In the in-circuit emulator, peripheral functions operate during a break, so there may be a difference between the
operations of the in-circuit emulator and target device.
(However, while the in-circuit emulator is in the break status, the counter of the watchdog timer stops.)
