MCP2150
2.8
The device can be placed in a low power mode by dis-
abling the device (holding the EN pin at the low state).
The internal state machine is monitoring this pin for a
low level and, once this is detected, the device is
disabled and enters into a low power state.
2.8.1
When disabled, the device is in a low power state.
When the EN pin is brought to a high level, the device
will return to the operating mode. The device requires
a delay of 1024 T
or received.

Model. The shaded areas are implemented by the
MCP2150, the cross-hatched area is implemented by
an infrared transceiver. The unshaded areas should be
implemented by the Host Controller.
