SIRQR2 is an 8-bit read/write register that indicates interrupt request in the servo section. If the
interrupt request has occurred, the corresponding bit is set to 1.
Writing 0 after reading 1 is allowed; no other writing is allowed. It is initialized to H'FC by a
reset, or in stand-by or module stop mode.
Bits 7 to 2
Reserved: Cannot be modified and are always read as 1.
