Setting the STI Enabled Bit
This selection determines if execution of the STI is allowed.
When this bit is set to
NO, execution of the STI is not allowed.
When this bit is set to
YES, execution of the STI is allowed (provided the STI
setpoint is non-zero). If reset when an interrupt occurs, the STI subroutine
does not execute and the STI Pending bit is set. The STI Timer continues to
run when this bit is disabled. The STE instruction sets this bit. The STD
instruction clears this bit.
To change the bit setting:
1. Put the controller in RPRG mode (if it is not already in that mode).
2. Access the program configuration menu.
3. Arrow up to the option
STI ENABLED and select it.
