5.3.27 Vector Number Setting Register U (VCRU)
Vector number setting register U (VCRU) is a 16-bit read/write register that sets the serial I/O 2
(SIO2) receive-data-full interrupt and transmit-data-empty interrupt vector numbers (0–127).
VCRU is initialized to H'0000 by a reset. It is not initialized in standby mode.

Bits 15 and 7—Reserved. These bits are always read as 0. The write value should always be 0.
Bits 14 to 8—Serial I/O 2 (SIO2) Receive-Data-Full Interrupt Vector Number 6 to 0 (RDF2V6–
RDF2V0): These bits set the vector number for the serial I/O 2 (SIO2) receive-data-full interrupt.
There are seven bits, so the value can be set between 0 and 127.
Bits 6 to 0—Serial I/O 2 (SIO2) Transmit-Data-Empty Interrupt Vector Number 6 to 0 (TDE2V6–
TDE2V0): These bits set the vector number for the serial I/O 2 (SIO2) transmit-data-empty
interrupt. There are seven bits, so the value can be set between 0 and 127.
Tables 5.6 and 5.7 show the relationship between on-chip peripheral module interrupts and
interrupt vector number setting registers.
