23.3.42 Relay Status Register (TSU_FWSR)
TSU_FWSR is a 32-bit readable/writable register that indicates the status during relay operations.
By setting the relay status interrupt mask register (TSU_FWINMK), this status can be notified to
the CPU as an interrupt source. The status bit set to 1 will be cleared to 0 by writing 1 to the
corresponding bit. (The status bit retains the value until it is cleared to 0.)
Interrupts generated due to this status register are identified as EINT2. For details on the priority
order of interrupts, see section 9.4.6, Interrupt Exception Handling and Priority in section 9,
Interrupt Controller (INTC).
If an error other than RBSY1 or RBSY0 occurs during relay operations, the corresponding relay
frame is discarded.
