DESCRIPTION
General-Purpose Input/Output
External Flag Output. XF is used for signaling other processors in multiprocessor
configurations or XF can be used as a fast general-purpose output pin.
XF is set high by the BSET XF instruction and XF is set low by the BCLR XF
instruction or by writing to bit 13 of the ST1_55 register. For more information on the
–
ST1_55 register, see the TMS320C55x 3.0 CPU Reference Guide (literature

number: SWPU073 ).
BH
For XF pin behavior at reset, see Section 5.7.2 , Pin Behaviors at Reset .
Note: This pin may consume static power if configured as Hi-Z and not externally
pulled low or high. Prevent current drain by externally terminating the pin. XF pin is
ONLY in the Hi-Z state when doing boundary scan. Therefore, external termination
is probably not required for most applications.
This pin is multiplexed between MMC0, I2S0, and GPIO.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal, BH = Bus Holder
Input pins of type I, I/O, and I/O/Z are required to be driven at all times. To achieve the lowest power, these pins must not be allowed to
float. When they are configured as input or high-impedance state, and not driven to a known state, they may cause an excessive IO-
supply current. Prevent this current by externally terminating it or enabling IPD/IPU, if applicable.
IPD = Internal pulldown, IPU = Internal pullup. For more detailed information on pullup/pulldown resistors and situations where external
pullup/pulldown resistors are required, see Section 3.8.1 , Pullup/Pulldown Resistors .
Specifies the operating I/O supply voltage for each signal
