Appendix B. AMX 68000 Service Procedures
B.1 Summary of Services
AMX 68000 provides a collection of target dependent AMX service procedures for use
with the M68000 processor and compatibles and the C compilers which support them.
These procedures are summarized below.
Interrupt Control (class
ksi)
cjksitrap Install a task trap handler
cjksivtp Fetch pointer to the AMX Vector Table
cjksivtrd Read an entry from the AMX Vector Table
cjksivtwr Write an entry into the AMX Vector Table
cjksivtx Exchange an entry in the AMX Vector Table
Processor and C Interface Procedures (class
cf)
In addition to the services provided by AMX and its managers, the AMX Library
includes several C procedures of a general nature which simplify application
programming in real-time systems on your target processor.
cjcfccsetup Setup C environment
cjcfdi Disable interrupts at priority level 6
cjcfei Enable interrupts at priority level 0
cjcfflagrd Read the processor status register (SR)
cjcfflagwr Write to the processor status register (SR)
