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.
