Step 3.a: SW3 Configuration
Set 1
The "On" DIP Switch position
corresponds to a signal value of
“zero”.
SW3.1-SW3.3
CFG_RS sets the Reset Configuration Words Source
ON: value of zero
factory setting: '000' when RCW is fetched from the local bus
DIP-switch SW9/3 FCFG: chooses between BCSR or Flash RCW source
SW3.4
CLKDIV selects the relationship between CLKIN and PCI_SYNC_OUT
if the MPC8349 is configured as a PCI Agent (factory setting) then CLK_DIV
is low
SW3.5-SW3.8
SPMF selects System PLL Multiplication Factor
factory setting: '0100'
clock ratio: csb_clk/CLKIN = 4 (csb_clk = 266MHz) or csb_clk/PCI_CLK = 4
Factory default setting: 00000101
Step 3.b: SW4 Configuration
Set 2
SW4.1-SW4.2: TSEC1/TSEC2
Selects the protocol used by the two-port TSEC controller
factory setting: enters GMII mode when TSEC1 and TSEC2 initiate similar
2’b10
SW4.5: BMS: Selects boot memory space
factory setting is ‘1’ when boot memory resides in upper eight Mbytes at
0xFF80_0000 to 0xFFFF_FFFF
SW4.6 TLE: Selects endian mode
factory setting: '0'; big endian mode
SW4.7: PCI64: Selects PCI width
factory setting: '0'; 32-bit width
SW4.8: FCFG: Sets RCW source on local bus
‘0’: BCSR source; setting uses values from SW3 and SW6.
‘1’: Flash source - setting is burned in flash memory
Factory setting: ‘0’
Factory default setting: 10101000
Step 3.c: SW6 Configuration
Set 3
SW6.1-SW6.2: Boot sequencer configuration
Boot sequencer loads configuration data from the serial ROM.
Factory setting: ‘00’; disables access to I2C ROM.
SW6.3-SW6.5: Boot ROM location
Factory setting: ‘110’; provides flash boot on local bus
SW6.6 DDR: Clock mode
Factory setting: ‘0’; operates with DDR clock (identical to csb_clk)
SW6.7: Local bus clock mode
Factory setting: ‘1’; operates with local bus clock - half of csb_clk
SW6.8: Software watchdog
Factory setting: ‘0’; with software watchdog disabled
Factory default setting: 00110010
