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
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-

and the interrupt code will not be cleared until a WRITE_CFG
command is received.

0xAA, otherwise no reset will occur and an error condition will
be signalled.
