APPENDIX 4 EXAMPLE OF CYCLIC HANDLER CODING
When creating a cyclic handler, be careful about the following points.
(1) The cyclic handler can be mapped in the 1MB memory space. (Large model only)
(2) The cyclic handler is invoked with the “br rg” command from the timer dispatch routine. For this reason, it is
handled in the same manner as an interrupt handler; therefore, the system calls that can be issued are only
the “i
′′′
_
′′′
” system calls. However, the “i
′′′
_
′′′
” system calls targeting cyclic handlers cannot be issued
from a cyclic handler.
(3) After ending the cyclic handler processing, be sure to return to the timer dispatch routine “tm_ret”. Please
code the cyclic handler processing as follows:
(4) When switching to another register bank in the cyclic handler, return to the original register bank first before
returning to the timer dispatch routine.
(5) In the timer dispatch routine, the “rg7, rg6, rg5, rp1, and rp0” registers are stored on the stack when
interrupted. Therefore, when using the “rg4, rp3, and rp2” registers in the cyclic handler, please restore the
value to the original one when returning to the timer dispatch routine.
