Vector Number Setting Register C (Vcrc) - Hitachi SH7095 Hardware User Manual

• 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) transmit-data-empty interrupt vector
number (STXV6–STXV0): These bits set the vector number for the serial communication
interface (SCI) transmit-data-empty interrupt (TXI). There are seven bits, so the value can be
set between 0 and 127.
• Bits 6 to 0—Serial communication interface (SCI) transmit-end interrupt vector number
(STEV6–STEV0): These bits set the vector number for the serial communication interface
(SCI) transmit-end interrupt (TEI). There are seven bits, so the value can be set between 0 and
127.

Vector Number Setting Register C (VCRC)

The vector number setting register C (VCRC) is a 16-bit read/write register that sets the FRT
input-capture interrupt and output-compare interrupt vector numbers (0–127). VCRC is initialized
to H'0000 on reset. It is not initialized in standby mode.

• Bits 15, 7—Reserved bits: These bits always read 0. The write value should always be 0.
• Bits 14 to 8—Free-running timer (FRT) input-capture interrupt vector number (FICV6–
FICV0): These bits set the vector number for the free-running timer (FRT) input-capture
interrupt (ICI). There are seven bits, so the value can be set between 0 and 127.
• Bits 6 to 0—Free-running timer (FRT) output-compare interrupt vector number (FOCV6–
FOCV0): These bits set the vector number for the free-running timer (FRT) output-compare
interrupt (OCI). There are seven bits, so the value can be set between 0 and 127.
