Description
Reserved
1 = The SPI3 TX block is reset.
1 = The SPI3 RX block is reset.
0 = Indicates that SPI3 block operates in 32-bit
MPHY mode.
1 = Indicates that the SPI3 block operates in 4 x 8
SPHY mode.
This configuration affects both the SPI3 transmitter
and receiver functionality.
Indicates whether to drop packets received with
parity error during the address selection phase
(Tsx and nTenb High) should be dropped.
0 = Do not drop packets with address parity error
1 = Drop packets with address parity error
This is applicable only in MPHY mode of
operation. This bit is ignored in SPHY (4 x 8) mode
as there will be no address selection.
SPHY/MPHY Mode:
Indicates whether to drop packets with data parity
error for port 3.
0 = Do not drop packets with data parity error
(default)
1 = Drop packets with data parity error
SPHY/MPHY Mode:
Indicates whether to drop packets with data parity
error for port 2.
0 = Do not drop packets with data parity error
(default)
1 = Drop packets with data parity error
SPHY/MPHY Mode:
Indicates whether to drop packets with data parity
error for port 1.
0 = Do not drop packets with data parity error
(default)
1 = Drop packets with data parity error
