5.3.10
Vector number setting register D (VCRD) is a 16-bit read/write register that sets the free-running
timer (FRT) overflow interrupt vector number (0–127). VCRD is initialized to H'0000 by a reset.
It is not initialized in standby mode.
Bits 15 and 7 to 0—Reserved: These bits are always read as 0. The write value should always be
0.
Bits 14 to 8—Free-Running Timer (FRT) Overflow Interrupt Vector Number 6 to 0 (FOVV6–
FOVV0): These bits set the vector number for the free-running timer (FRT) overflow interrupt
(OVI). There are seven bits, so the value can be set between 0 and 127.
