• Bits 15, 7—Reserved bits: These bits always read 0. The write value should always be 0.
• Bits 14 to 8—Serial communication interface (SCI) receive-error interrupt vector number
(SERV6–SERV0): These bits set the vector number for the serial communication interface
(SCI) receive-error interrupt (ERI). There are seven bits, so the value can be set between 0
and 127.
• Bits 6 to 0—Serial communication interface (SCI) receive-data-full interrupt vector number
(SRXV6–SRXV0): These bits set the vector number for the serial communication interface
(SCI) receive-data-full interrupt (RXI). There are seven bits, so the value can be set between 0
and 127.

Vector Number Setting Register B (VCRB)

The vector number setting register B (VCRB) is a 16-bit read/write register that sets the SCI
transmit-data-empty interrupt and transmit-end interrupt vector numbers (0–127). VCRB is
initialized to H'0000 on reset. It is not initialized in standby mode.
