Boot Configuration
Table 3-13. Boot Configuration Terminal Functions
SIGNAL NAME [1]
DESCRIPTION [2]
TYPE [3]
AAR BALL [4]
BTMODE[0]
Boot Mode Selection 0. ARM Cortex-A8 Boot Mode
I
W6
Configuration Bits. This pin is multiplexed between ARM
Cortex-A8 boot mode and the General-Purpose Memory
Controller (GPMC) peripheral functions. At reset, the boot
mode inputs BTMODE[4:0] are sampled to determine the
ARM boot configuration. For more details on the types of
boot modes supported, see Section 4.2, Boot Modes, of
this document, along with the ROM Code Memory and
Peripheral Booting chapter of the device Technical
Reference Manual. After reset, this pin functions as
GPMC multiplexed data/address pin 0 (GPMC_D[0]).
BTMODE[1]
Boot Mode Selection 1. ARM Cortex-A8 Boot Mode
I
W4
Configuration Bits. This pin is multiplexed between ARM
Cortex-A8 boot mode and the General-Purpose Memory
Controller (GPMC) peripheral functions. At reset, the boot
mode inputs BTMODE[4:0] are sampled to determine the
ARM boot configuration. For more details on the types of
boot modes supported, see Section 4.2, Boot Modes, of
this document, along with the ROM Code Memory and
Peripheral Booting chapter of the device Technical
Reference Manual. After reset, this pin functions as
GPMC multiplexed data/address pin 1 (GPMC_D[1]).
BTMODE[2]
Boot Mode Selection 2. ARM Cortex-A8 Boot Mode
I
W3
Configuration Bits. This pin is multiplexed between ARM
Cortex-A8 boot mode and the General-Purpose Memory
Controller (GPMC) peripheral functions. At reset, the boot
mode inputs BTMODE[4:0] are sampled to determine the
ARM boot configuration. For more details on the types of
boot modes supported, see Section 4.2, Boot Modes, of
this document, along with the ROM Code Memory and
Peripheral Booting chapter of the device Technical
Reference Manual. After reset, this pin functions as
GPMC multiplexed data/address pin 2 (GPMC_D[2]).
BTMODE[3]
Boot Mode Selection 3. ARM Cortex-A8 Boot Mode
I
U2
Configuration Bits. This pin is multiplexed between ARM
Cortex-A8 boot mode and the General-Purpose Memory
Controller (GPMC) peripheral functions. At reset, the boot
mode inputs BTMODE[4:0] are sampled to determine the
ARM boot configuration. For more details on the types of
boot modes supported, see Section 4.2, Boot Modes, of
this document, along with the ROM Code Memory and
Peripheral Booting chapter of the device Technical
Reference Manual. After reset, this pin functions as
GPMC multiplexed data/address pin 3 (GPMC_D[3]).
BTMODE[4]
Boot Mode Selection 4. ARM Cortex-A8 Boot Mode
I
W9
Configuration Bits. This pin is multiplexed between ARM
Cortex-A8 boot mode and the General-Purpose Memory
Controller (GPMC) peripheral functions. At reset, the boot
mode inputs BTMODE[4:0] are sampled to determine the
ARM boot configuration. For more details on the types of
boot modes supported, see Section 4.2, Boot Modes, of
this document, along with the ROM Code Memory and
Peripheral Booting chapter of the device Technical
Reference Manual. After reset, this pin functions as
GPMC multiplexed data/address pin 4 (GPMC_D[4]).
BTMODE[5]
Boot Mode Selection 5. Reserved Boot Pin. This pin is
I
T5
multiplexed between ARM Cortex-A8 boot mode and
General-Purpose Memory Controller (GPMC) peripheral
functions. For proper device operation at reset, this pin
should be externally pulled low. After reset, this pin
functions as GPMC multiplexed data/address pin 5
(GPMC_D[5]).
