DESCRIPTION
EMIFA: BOOT CONFIGURATION
IPD
DV_DD33
IPD
DV_DD33
DV_DD33
These pins are multiplexed between the VPBE (VENC), EMIFA, and
GPIO. When RESET or POR is asserted, these pins function as
EMIFA configuration pins. At reset if AEM[2:0] = 001 (EMIFA in 8-bit
Async mode), then the input states of AEAW[2:0] are sampled to set
the EMIFA Address Bus Width. After reset, these pins function as
VPBE (VENC), EMIFA, or GPIO pin functions based on pin mux
selection.
For more details on the AEAW/PLLMS functions, see Section 3.5.1.2,
EMIFA Address Bus Width (AEAW) and Fast Boot PLL Multiplier
Select (PLLMS).

These pins are multiplexed between the VPBE (VENC), EMIFA, and
GPIO. When RESET or POR is asserted, these pins function as
EMIFA configuration pins. At reset, the input states of AEM[2:0] are
sampled to set the EMIFA Pinout Mode.
For more details, see Section 3.5.1, Configurations at Reset. After
reset, these pins function as VPBE (VENC), EMIFA, or GPIO pin
functions based on pin mux selection.
For more details on the AEM functions, see Section 3.5.1.1, EMIFA
Pinout Mode (AEM[2:0]).
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) 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 3.9.1, Pullup/Pulldown Resistors.
(3) Specifies the operating I/O supply voltage for each signal
