REF_CLK

Reference clock. This bit reflects the current state of the 28.8 KHz reference clock derived from the 1.8432 MHz UART oscillator divided by 64. This clock may be used as a fixed timing reference.

BANK_SEL

Boot Flash bank select. This bit reflects the current state of the boot Flash bank select jumper. A cleared condition indicates that Flash bank A is the boot bank. A set condition indicates that Flash B is the boot bank.

SAFE_START

ENV safe start. This bit reflects the current state of the ENV safe start select jumper. A set condition indicates that MOTLoad should provide the user the capability to select which Boot Image is used to boot the board, cleared MOTLoad should proceed with the first boot image found.
