Struct probe_rs::architecture::arm::dp::RdBuff

pub struct RdBuff(pub u32);

RDBUFF, Read Buffer register (see ADI v5.2 B2.2.7)

The purpose and behavior of RDBUFF is DATA LINK DEFINED:

JTAG-DP: The Read Buffer is architecturally defined to provide a DP read operation that does not have any side effects. This definition allows a debugger to insert a DP read of RDBUFF at the end of a sequence of operations, to return the final AP Read Result and ACK values.

SW-DP:* On an SW-DP, the Read Buffer presents data that was captured during the previous AP read, enabling repeatedly returning the value without generating a new AP access.

Note

After reading the DP Read Buffer, its contents are no longer valid. The result of a second read of the DP Read Buffer is UNKNOWN.

If you require the value from an AP register read, that read must be followed by one of:

• A second AP register access, with the appropriate AP selected as the current AP.
• A read of the DP Read Buffer.

The second access to either the AP or the DP stalls until the result of the original AP read is available.
