EEPROM Write Protect. This bit is to provide protection against
inadvertent writes to the on-board EEPROM devices. Clearing this
bit will enable writes to the EEPROM devices. Setting this bit write
protects the devices. The devices are write protected following a
reset.
Board Reset. These bits are used to force a hard reset of the board.
If a pattern is written in bits 5-7 where bit 7 is set, bit 6 is cleared, and
bit 5 is set (101), a hard reset is generated. Any other pattern written
in bits 5-7, does not generate a hard reset. These bits are cleared
automatically when the board reset has been completed. These bits
are always cleared during a read.
Reserved for future implementation.
