Configuration pins — CPU

None of the 64 GPIO pins on connector X2 disturb CPU boot strap functions. The

boot strap functions are controlled by address signals; the user can not disturb boot

strap functions from outside, if the module configuration signals, described below,

are correctly configured.

Default module

configuration

The user has access to six configuration signals:

 LITTLE#/BIG_ ENDIAN which allows the user to select the endianess of the

module

 OCD_EN# which allows the user to activate on-chip debugging

 SW_CONF [3:0] which are reserved for the user; the user software can read out

these signals through the GEN ID register
