Description
Local GPIO Output Value This value is the
output on the GPIO pin when the GPIO function
is enabled, the local GPIO direction is Output.
Reserved.
Local GPIO Direction.
1: Input.
0: Output.
GPIO Function Enable.
1: Enable GPIO operation.
0: Enable normal operation.
Local GPIO Output Value This value is output
on the GPIO pin when the GPIO function is
enabled, the local GPIO direction is Output.
Reserved.
Local GPIO Direction.
1: Input.
0: Output.
GPIO Function Enable.
1: Enable GPIO operation.
0: Enable normal operation.
Allows overriding OEN and OSS select coming
from Pins.
1: Overrides OEN/OSS_SEL selected by pins.
0: Does NOT override OEN/OSS_SEL select
by pins.
OEN configuration from register.
OSS_SEL configuration from register.
Allows overriding mode select bits coming from
forward-channel.
1: Overrides MODE select bits.
0: Does not override MODE select bits.
Status of mode select pin.
Status of mode select pin.
Selects 12-bit high frequency mode. This bit is
automatically updated by the mode settings
from MODE pin unless MODE_OVERRIDE is
SET.
1: 12-bit high frequency mode is selected.
0: 12-bit high frequency mode is not selected.
Selects 10-bit mode. This bit is automatically
updated by the mode settings from MODE pin
unless MODE_OVERRIDE is SET.
1: Enables 10-bit mode.
0: Disables 10-bit mode.
The 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.
Disable Bidirectional Control Channel
Watchdog Timer.
1: Disables BCC Watchdog Timer operation.
0: Enables BCC Watchdog Timer operation.
