pullup/pulldown resistor on the HD5 pin:

HD24/AD24§

pullup/pulldown resistor on the HD5 pin:

HD5 pin = 0: HPI operates as an HPI16.

HD23/AD23§

reserved pins in the high-impedance state.)

HD5 pin = 1: HPI operates as an HPI32.

HD20/AD20§

HD5 pin = 1: HPI operates as an HPI32.

(HPI bus is 32 bits wide. All HD[31:0] pins are used for host-port operations.)

HD19/AD19§

(HPI bus is 32 bits wide. All HD[31:0] pins are used for host-port operations.)

HD18/AD18§

Used for transfer of data and address

HD17/AD17§

• Used for transfer of data and address

HD16/AD16§

HD15/AD15§

† I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground

‡ IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the opposite

supply rail, a 1-k

Ω resistor should be used, unless otherwise noted.)

§ These pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
