1.3 Development Tools
Note: There are several setting switches in the Emulator.
User should read carefully and do setting properly before
developing the program refer to "24.2 Emulator S/W Set-
ting" on page 84. Otherwise, the Emulator may not work
properly.
The GMS81C5108 is supported by a full-featured macro assem-
bler, an in-circuit emulator CHOICE-Dr.
TM
and OTP program-
mers. There are two different type programmers such as single
type and gang type. For mode detail, refer to OTP Programming
chapter. Macro assembler operates under the MS-Windows 95/
98
TM
.
Please contact sales part of Hynix Semiconductor.
