17.3 READ_INT COMMAND
The READ_INT command consists of a command byte (0x82)
from the host and a data byte from the LM8322. The data byte
is the interrupt code. Reading the interrupt code acknowl-
edges the interrupt (which deasserts IRQ) and clears the
interrupt code. An exception to this behavior occurs if the
NOINIT bit is set, in which case IRQ will not be deasserted
and the interrupt code will not be cleared until a WRITE_CFG
command is received.

Description
PWM2END
0
No interrupt from PWM channel 2.
1
An END script command was executed by PWM channel 2.
PWM1END
0
No interrupt from PWM channel 1.
1
An END script command was executed by PWM channel 1.
PWM0END
0
No interrupt from PWM channel 0.
1
An END script command was executed by PWM channel 0.
NOINIT
0
Normal operation.
1
LM8322 is waiting for the initialization sequence.
ERROR
0
No error condition is indicated.
1
An error condition occurred.
KEYPAD
0
No key-press or key-release event is indicated.
1
A key-press or key-release event occurred.
17.4 RESET COMMAND
The RESET command consists of a command byte (0x83)
and one data byte from the host. The command causes a re-
set, identical to an external reset. The data byte must be
0xAA, otherwise no reset will occur and an error condition will
be signalled.
