Output Async EMIF: Address Bus bit[02]
HPI: The state of HCNTLA and HCNTLB determines
if address, data, or control information is being
transmitted between an external host and the device.
Note: HPI is pin multiplexed with Asynchronous
EMIF at the output pin. HPI is available only when
boot mode selected is HPI boot mode. In this
configuration, the device will always act as a slave.

Output Async EMIF: Address Bus bit[01]
HPI: This pin is half-word identification input HHWIL.
Note: HPI is pin multiplexed with Asynchronous
EMIF at the output pin. HPI is available only when
boot mode selected is HPI boot mode. In this
configuration, the device will always act as a slave.

HPI: This pin is host interrupt output HINT
Note: HPI is pin multiplexed with Asynchronous
EMIF at the output pin. HPI is available only when
boot mode selected is HPI boot mode. In this
