Description
Port GPIO(0);
Port GPIO(1);
Port GPIO(2);
Port GPIO(3);
Port GPIO(4);
Port GPIO(5);
Port GPIO(6);
Port GPIO(7);
Port GPIO(8);
If the ETM9 module is activated via debug SW and it is set as a 4- to 8-bit
wide ETM port, function 3 (ETM:TRACEPKT(0) is set regardless of the
value of GPIO_PORT_MODE_L-bits (17:16).
This applies analogously to GPIO_PORT_MODE_L-bits (23:18) and ETM
pins TRACEPKT(3:1).
Port GPIO(9);
