8.10.1.1 Configuring Boot Mode Pins

This section explains how the boot mode select pins can be customized by the user, by programming the BOOTPIN-CONFIG location (refer to Table 8-8) in the user-configurable dual-zone security module (DCSM) OTP. The location in the DCSM OTP is Z1-OTP-BOOTPIN-CONFIG or Z2-OTP-BOOTPIN-CONFIG. When debugging, EMU-BOOTPIN-CONFIG is the emulation equivalent of Z1-OTP-BOOTPIN-CONFIG/Z2-OTP-BOOTPIN-CONFIG, and can be programmed to experiment with different boot modes without writing to OTP. The device can be programmed to use 0, 1, 2, or 3 boot mode select pins as needed.

Note:

When using Z2-OTP-BOOTPIN-CONFIG, the configurations programmed in this location will take priority over the configurations in Z1-OTP-BOOTPIN-CONFIG. It is recommended to use Z1-OTP-BOOTPIN-CONFIG first and then if OTP configurations need to be altered, switch to using Z2-OTP-BOOTPIN-CONFIG.

Table 8-8 BOOTPIN-CONFIG Bit Fields
BITNAMEDESCRIPTION
31:24KeyWrite 0x5A to these 8-bits to indicate the bits in this register are valid
23:16Boot Mode Select Pin 2 (BMSP2)Refer to BMSP0 description except for BMSP2
15:8Boot Mode Select Pin 1 (BMSP1)Refer to BMSP0 description except for BMSP1
7:0Boot Mode Select Pin 0 (BMSP0)

Set to the GPIO pin to be used during boot (up to 255):
- 0x0 = GPIO0
- 0x01 = GPIO1
- and so on

Writing 0xFF disables BMSP0 and this pin is no longer used to select the boot mode.

The following GPIOs cannot be used as a BMSP. If selected for a particular BMSP, the boot ROM automatically selects the factory default GPIO (the factory default for BMSP2 is 0xFF, which disables the BMSP).

  • GPIO 20 and GPIO 21
  • GPIO 36 and GPIO 38
  • GPIO 47 to GPIO 60
  • GPIO 63 to GPIO 223

Note:

When decoding the boot mode, BMSP0 is the least-significant-bit and BMSP2 is the most-significant-bit of the boot table index value. It is recommended when disabling BMSPs to start with disabling BMSP2. For example, in an instance when only using BMSP2 (BMSP1 and BMSP0 are disabled), then only the boot table indexes of 0 and 4 will be selectable. In the instance when using only BMSP0, then the selectable boot table indexes are 0 and 1.
