Interrupt system

23/54

INT_EN

Interrupt enable register

Address:

0x0A

Type:

R/W

Reset:

0x00

Description:

The interrupt enable register is used to enable the interruption from a system related

interrupt source to the host.

INT_STA

Interrupt status register

Address:

0x0B

Type:

Reset:

0x10

Description:

The interrupt status register monitors the status of the interruption from a particular

interrupt source to the host. Regardless of whether the INT_EN bits are enabled, the

INT_STA bits are still updated. Writing '1' to this register clears the corresponding

bits. Writing '0' has no effect.
