undocumented test functionality and can cause unpredictable behavior if they are unnecessarily
connected to a pull-up or pull-down resistor.

Flash/Modem Data Input/Output. These pins are used for Flash/
Modem data interface. These pins should be left floating if the Flash
and modem are not used.
Flash Address[16]/25 MHz Clock. This multiplexed pin is controlled
by the status of the Flash Address[7] (FLA[7]) pin. If FLA[7] is left
floating, this pin is used as FLA[16]; otherwise, if FLA[7] is connected
to a pull-up resistor, this pin is used as a 25 MHz clock. This pin should
be left floating if the Flash and CLK25 functionality are not used.
Flash Address[15]/EEPROM Data Output. During Flash accesses,
this multiplexed pin acts as the Flash Address [15] output signal.
During EEPROM accesses, it acts as the serial shift clock output to
the EEPROM.
Flash Address[14]/EEPROM Data Output. During Flash accesses,
this multiplexed pin acts as the Flash Address [14] output signal.
During EEPROM accesses, it accepts serial input data from the
EEPROM Data Output signal.
Flash Address[13]/EEPROM Data Input. During Flash accesses,
this multiplexed pin acts as the Flash Address [13] output signal.
During EEPROM accesses, it provides serial output data to the
EEPROM Data Input signal.
Flash Address[12]/Modem Central Site Mode. This multiplexed pin
acts as the Flash Address[12] output signal in a non-modem card. If
modem is enabled, it is used as an output signal to the modem. It is
either floated by default or driven low by the Modem System Control
Registers. This pin should be left floating if the Flash and modem
functionality are not used.
Flash Address[11]/Modem Interrupt. This multiplexed pin acts as
the Flash Address[11] output signal in a non-modem card. If modem is
enabled, it is used as the Modem Interrupt input signal. This pin should
be left floating if the Flash and modem functionality are not used.
Flash Address[10]/Modem Ring. This multiplexed pin acts as the
Flash Address[10] output signal in a non-modem card. If modem is
enabled, it is used as the Modem Ring input signal. This pin should be
left floating if the Flash and modem functionality are not used.
Flash Address[9]/Modem Reset. This multiplexed pin acts as the
Flash Address[9] output signal in a non-modem card. If modem is
enabled, it acts as the Modem Reset signal with an active high output.
This pin should be left floating if the Flash and modem functionality are
not used.
Flash Address[8]/ISA Input/Output Channel Ready. This
multiplexed pin acts as the Flash Address[8] output signal in a non-
modem card. If modem is enabled, it is used as the ISA IOCHRDY
input signal. This pin should be left floating if the Flash and modem
functionality are not used.
