9 Read Resend Register, RESEND

The RESEND register enables the read data to be recovered from a corrupted debugger transfer without repeating the original AP transfer.

For JTAG-DP, this register is Reserved and any access is RES0. For SW-DP, a read to this register does not capture new data from the AP, but returns the value that was returned by the last AP read or DP RDBUFF read.
