Description
Local GPIO2 Output Value. This value is output
on the GPIO2 pin when GPIO2 is enabled, and
the local GPIO2 direction is set to output.
Reserved.
Local GPIO2 direction:
1: Input.
0: Output.
GPIO2 enable:
1: Enable GPIO2 operation.
0: TRI-STATE.
Local GPIO3 Output Value. This value is output
on the GPIO3 pin when GPIO3 is enabled, and
the local GPIO3 direction is set to output.
Reserved.
Local GPIO3 direction:
1: Input.
0: Output.
GPIO3 enable:
1: Enable GPIO3 operation.
0: TRI-STATE.
Local GPIO0 Output Value. This value is output
on the GPIO0 pin when GPIO0 is enabled, and
the local GPIO0 direction is set to output.
Reserved.
Local GPIO0 direction:
1: Input.
0: Output.
GPIO0 enable:
1: Enable GPIO0 operation.
0: TRI-STATE.
Local GPIO1 Output Value. This value is output
on the GPIO1 pin when GPIO1 is enabled, and
the local GPIO1 direction is set to output.
Reserved.
Local GPIO1 direction:
1: Input.
0: Output.
GPIO1 enable:
1: Enable GPIO1 operation.
0: TRI-STATE.
Allows overriding OEN and OSS_SEL coming
from pins.
1: Overrides OEN/OSS_SEL selected by pins.
0: Does NOT override OEN/OSS_SEL selected
by pins.
OEN configuration register.
OSS_SEL configuration register.
Reserved.
The BCC Watchdog Timer allows termination of
a control channel transaction if it fails to
complete within a programmed amount of time.
This field sets the Bidirectional Control Channel
Watchdog timeout value in units of 2ms. This
field should not be set to 0.
Bidirectional Control Channel Watchdog Timer
enable.
1: Disables BCC Watchdog Timer operation.
0: Enables BCC Watchdog Timer operation.
