Notes: 1. The value when the NMI pin is high is H'8000; when the NMI pin is low, it is H'0000.

2. When pins

IRL3–IRL0 are high, bits 7–4 in IRQCSR are set to 1. When pins IRL3–IRL0

are low, bits 7–4 in IRQCSR are cleared to 0. The initial value of bits other than 7–4 is

3. In the SH7616, VCRB is a reserved register and must not be accessed.

4. See section 11, Direct Memory Access Controlle for more information on VCRDMA0,

and VCRDMA1.

Interrupt Sources

There are five types of interrupt sources: NMI, user breaks, H-UDI, IRL/IRQ and on-chip

peripheral modules. Each interrupt has a priority expressed as a priority level (0 to 16, with 0 the

lowest and 16 the highest). Giving an interrupt a priority level of 0 masks it.
