GPTA, V2.0
– External port lines
– Local Timer Cell outputs
– Filter and Prescaler Cell outputs
– Internal input signals INTx
• Two action mode inputs (M0I, M1I) coming from the adjacent GTC with lower order
number (M1I and M0I of GTC00 are 0)
Each GTC provides the following outputs:
• One data output (GTCkOUT) that can be connected to:
– External port lines
– Inputs of an MSC module
– Outputs and/or inputs of Local Timer Cell inputs
• Two action mode outputs (M0O, M1O) going to the adjacent GTC with higher order
number
• One service request line (SQSk) triggered by a capture/compare event.
