Notes:
1. Refer to the Platform Design Guide for circuit implementations for these signals.
2.4 Power-On Configuration (POC) Options
Functional options can be configured by hardware strapping of input signals. The
processor samples its hardware configuration at reset, on the active-to-inactive
transition of RESET_N, or upon assertion of PWRGOOD (inactive-to-active transition).
Configuration options are described in Table 2-6.
The sampled input configures the processor for subsequent operation. These
configuration options cannot be changed except by another reset transition of the
latching signal (RESET_N or PWRGOOD).
Notes:
1. PROCHOT_N for FRB mode is latched at de-assertion of RESET_N. Output high-impedance option enables
Fault Resilient Booting (FRB) as detailed in Section 2.5.
2. BIST_ENABLE is sampled at de-assertion of RESET_N.
