HA1
GPIOB9
Input
Input/Output
Host Address (HA1)—This input provides the address selection for HI
registers.
This pin is disconnected internally.
Port B GPIO (9)—This pin is a General Purpose I/O (GPIO) pin when not
configured for host port usage.
64
HA2
GPIOB10
Input
Input/Output
Host Address (HA2)—This input provides the address selection for HI
registers.
This pin is disconnected internally.
Port B GPIO (10)—This pin is a General Purpose I/O (GPIO) pin when
not configured for host port usage.
65
HRWB
HRD
GPIOB11
Input
Input/Output
Host Read/Write (HRWB)—When the HI08 is programmed to interface
to a single-data-strobe host bus and the HI function is selected, this
signal is the Read/Write input.
These pins are disconnected internally.
Host Read Data (HRD)—This signal is the Read Data input when the
HI08 is programmed to interface to a double-data-strobe host bus and the
HI function is selected.
Port B GPIO (11) —This pin is a General Purpose I/O (GPIO) pin when
not configured for host port usage.
83
HDS
HWR
GPIOB12
Input
Input/Output
Host Data Strobe (HDS)—When the HI08 is programmed to interface to
a single-data-strobe host bus and the HI function is selected, this input
enables a data transfer on the HI when HCS is asserted.
These pins are disconnected internally.
Host Write Enable (HWR)—This signal is the Write Data input when the
HI08 is programmed to interface to a double-data-strobe host bus and the
HI function is selected.
Port B GPIO (12)—This pin is a General Purpose I/O (GPIO) pin when
not configured for host port usage.
84
HCS
GPIOB13
Input
Input/Output
Host Chip Select (HCS)—This input is the chip select input for the Host
Interface.
These pins are disconnected internally.
Port B GPIO (13)—This pin is a General Purpose I/O (GPIO) pin when
not configured for host port usage.
