One Shot Mode
In One Shot Mode (GTCCTRk.OSM = 1), a self-disable of GTCk is executed after each
GTC event (GTCCTRk.CEN = 0). The current state of a GTCk can be evaluated by
reading the control register flag bit GTCCTRk.CEN.
Note: The contents of the GTCk capture/compare register GTCXRk are write-protected
for Capture_After_Compare in Single Shot Mode. Write protection is activated
when the compare value is reached and released after a read access of register
GTCXRk occurred.
Data Output Line Control
The data output GTCkOUT can be controlled by the GTCk itself and by adjacent GTCs
with a lower order number. For this purpose, two communication signals between GTCs
are available connecting all GTCs via their M1I/M0I inputs and their M1O/ M0O outputs,
respectively (see Figure 24-45).
