A description of the function of each of the switches is given below:
sw2_1
Master/Slave select is used, in dual control situations, to assign Master/Slave
status to the 2440 control cards. One card would be set to MASTER and the other to
SLAVE so that on reset or power up the Master 2440 powers up first and, hence,
always becomes the active controller.
Sw2_2
m
P clock select is used to select between 10 MHz and 20MHz uP clock
frequency.
