Possible configurations
The selection of the bridge configuration is done through SPI, by writing the MtrXTable[1:0]
bits in the MtrXCfg register. The table below shows the correspondence between
MtrXTable[1:0] bits and the bridge configuration.
Bridge 1 & 2 can be paralleled by means of Mtr1_2Parallel bit in the Mtr1_2Cfg register:
Bridge 1 and 2 paralleled will form superbridge1, bridge X side A and bridge X side B
paralleled form SuperHalfBridgeX or SuperSwitchX.
Bridge 3 & 4 can be configured by means of Mtr3_4CfgTable[1:0] bits in the Mtr3_4Cfg
register according to following table:
The possible configurations for the bridges are described in the following.
Table 16.
