The transfer error status register contains a bit for each exception source generated
by a transfer error. A bit set to logic 1 indicates what type of transfer error exception
occurred since the last time the bits were cleared by reset or by the normal software
status bit-clearing mechanism. Note that these bits may be set due to canceled spec-
ulative accesses which do not cause an interrupt. The register has two identical sets
of bit fields; one is associated with instruction transfers and the other with data trans-
fers.

SWT servicing sequence is written to this register. To prevent SWT time-out, the user should
write a 0x556C followed by 0xAA39 to this register. The SWSR can be written at any time but
returns all zeros when read.
