Reserved
Notes: 1. An external vector number fetch can be performed without using the auto-vector
156
2. Vector numbers are set in the on-chip vector number register.
3. REF is the refresh control unit within the bus state controller.
4. Set to IRL1–IRL15 or IRQ0–IRQ3 by the EXIMD bit in ICR.
5. In the SH7615, VCRB (14–0) is a reserved register and must not be accessed.
6. The E-DMAC interrupt (EINT) is the OR of those of the 19 interrupt sources in the

EtherC/E-DMAC status register (EESR) that are enabled by the EtherC/E-DMAC status
interrupt permission register (EESIPR). As the three status bits in the EtherC status
register (ECSR) can be copied into the ECI bit in EESR as an interrupt source, EINT is
input to the INTC as the OR of a maximum of 21 interrupt sources.
