Function
These bits are not implemented.
Contains the status of the eFuses that
determine the type of device.
00: Production (normal) device
01: Bad device
10: Emulator device
11: Test device
Contains the status of GPIO1 input pin. Value
is latched on the rising edge of
PWRON_RESET.
For internal boot, software configures the
external chip-select after reading this bit.
For external boot, the external chip-select
configuration is forced after reading this bit.
0: Nonaddress/data multiplexed
1: Address/data multiplexed
This bit contains information about EMIFS
protocol at boot.
0: Nonaddress/data multiplexed
1: Address/data multiplexed
Reset value for this signal depends on GPIO1,
MPU_BOOT, and EFUSE_DEVICE_TYPE
signals.
