14.33.1 Interrupt Enable Registers

The Interrupt Enable registers:

LOS Interrupt En-

able Register (06h)

(See Section 14.7 on page 36),

DFM Interrupt Enable Register (07h)

(See Sec-

tion 14.8 on page 36),

AIS Interrupt Enable Reg-

ister (14h)

(See Section 14.21 on page 39)

,

enable

changes in status register state to cause an interrupt
on the INT pin. Interrupts are maskable on a per
channel basis. When an Interrupt Enable register
bit is 0, the corresponding Status register bit is dis-
abled from causing an interrupt on the INT pin.

NOTE: Disabling an interrupt has no effect on the sta-

tus reflected in the associated status register.

14.33.2 Interrupt Status Registers

The following interrupt status registers:

LOS In-

terrupt Status Register (08h)

(See Section 14.9

on page 36),

DFM Interrupt Status Register

(09h)

(See Section 14.10 on page 36),

AIS Inter-

rupt Status Register (15h)

(See Section 14.22 on

page 39)

,

indicate a change in status of the corre-

sponding status registers in host mode. Reading
these registers clears the interrupt, which deacti-
vates the INT pin.
