3.4.2.3 BOOTCFG Register
The Boot Configuration (BOOTCFG) register is a read-only register that indicates the value of the device
bootmode and configuration pins latched at the end of reset. During a hard reset (POR or RESET pin
active [low]), the values of the CFG pins (i.e., BTMODE[3:0], CS2BW, PCIEN, DSPBOOT) are propagated
through the BOOTCFG register to the Boot Controller. When RESET or POR is de-asserted, the value of
the pins is latched. The BOOTCFG value does not change as a result of a soft reset, instead the value
latched at the end of the previous global reset is retained.
