connector.

3.2.1.31 readAP
Reads from a CoreSight AP register.
This command performs a full-qualified read which means that it tries to read until
the read has been accepted or too many WAIT responses have been received.
In case actual read data is returned on the next read request (this is the case for
example with interface JTAG) this command performs the additional dummy read
request automatically.
Syntax
ReadAP <RegIndex>
Example
//
// Read AP[0], IDR (register 3, bank 15)
//
WriteDP 2, 0x000000F0 // Select AP[0] bank 15
ReadAP 3 // Read AP[0] IDR
