13. Why is the state changes of port not reflected in the Pinview window?
The pinview module gives an snapshot of the microcomputer pins at constant interval. It is not an
ocsilloscope that can snap signal as fast as 2ns. It is a tool used to help user to have a feel of the status of
the microcomputer pins. It will be very helpful when it is at static state. User can track any discontinuity
in the emulator to target connection.
14. Why can’t the two Mbytes of optional memory be utilized fully?
The two Mbytes of optional memory consists of 4 x 512Kbytes of memory. Each memory is selected
based on the upper address. Thus, if user intends to use the whole memory at a starting address that is
not multiple of 512Kbytes, user will not be able to utilize the full memory capacity (e.g. if the external
address begin at H’20000). However, if external address begin at H’0, as in the ROMless mode, user will
be able to map the whole 2Mbytes space (H’0 to H’1F FFFF).
15. Why can’t the OTP work as accordingly?
User has to note the differences as stated in the user manual, such as the initialization of registers (SP…),
the delay of signals (about 4ns of cabling delay…), the unused pins (OSC1, OSC2, CVCC…), the
regenerated power supply for emulator, the smoothed main clock signal, …
16. Why is the selection of “target clock “ not available in the system setup window?
HEW will disallow the target selection if the target is not available (The Signal CABLE_IN_N is Hi).
