SYS_CFGCTRL function values
Table 4-19 shows the different function values with their range of data values that the
SYS_CFGDATA represents.
[17:16] Site Describes the board site location of the device written to:
b00 Motherboard.
b01 Daughterboard 1.
b10 Daughterboard 2.
b11 Not used.
[15:12] Position Describes the board stack position:
4-bit number for the position of the daughterboard in the stack 0-15 on a particular
site. 0 represents the bottom of the stack. Set to 0 for the motherboard.
[11:0] Device 12-bit number that describes the device number. For example, oscillator 1 would be
device 1.
