Parameter
ABORT hold time from MCLKf
ABORT set up time to MCLKf
Asynchronous interrupt guaranteed nonrecognition time, with ISYNC=0
Asynchronous interrupt set up time to MCLKf for guaranteed recognition, with ISYNC=0
Reset guaranteed nonrecognition time
Reset setup time to MCLKr for guaranteed recognition
Figure 7-11 shows the ARM7TDMI processor exception timing. The timing parameters
used in Figure 7-11 are listed in Table 7-11.
In Figure 7-11, to guarantee recognition of the asynchronous interrupt (ISYNC=0) or
reset source, the appropriate signals must be setup or held as follows:
These inputs can be applied fully asynchronously where the exact cycle of recognition
is unimportant.
