User Interrupt Latency
The user interrupt latency is the maximum time from when an interrupt condition
occurs (e.g., STI expires or HSC preset is reached) to when the user interrupt
subroutine begins executing (assumes that there are no other interrupt conditions
present).
If you are communicating with the controller, the maximum user interrupt latency is
872
µ
s. If you are not communicating with the controller, the maximum user
interrupt latency is 838
µ
s.
