Description
BIST BC Error
Port0/Port1
BIST back channel CRC error counter.
This register stores the back channel CRC error count during BIST
Mode (saturates at 255 errors). Clears when a new BIST is initiated or
by 0x04[5].
If PORT1_SEL is set, this register indicates Port1 operation.
GPIO7_REG Pin GPIO7_REG input pin status.
Status
Note: status valid only if pin is set to GPI (input) mode.
GPIO6_REG Pin GPIO6_REG input pin status.
Status
Note: status valid only if pin is set to GPI (input) mode.
GPIO5_REG Pin GPIO5_REG input pin status.
Status
Note: status valid only if pin is set to GPI (input) mode.
Reserved.
GPIO3 Pin
Status
D_GPIO3 Pin
Status
GPIO3 input pin status.
Note: status valid only if pin is set to GPI (input) mode.
If PORT1_SEL is set, this register indicates D_GPIO3 operation.
GPIO2 Pin
Status
D_GPIO2 Pin
Status
GPIO2 input pin status.
Note: status valid only if pin is set to GPI (input) mode.
If PORT1_SEL is set, this register indicates D_GPIO2 operation.
GPIO1 Pin
Status
D_GPIO1 Pin
Status
GPIO1 input pin status.
Note: status valid only if pin is set to GPI (input) mode.
If PORT1_SEL is set, this register indicates D_GPIO1 operation.
GPIO0 Pin
Status
D_GPIO0 Pin
Status
GPIO0 input pin status.
Note: status valid only if pin is set to GPI (input) mode.
If PORT1_SEL is set, this register indicates D_GPIO0 operation.
Reserved
GPIO8_REG Pin GPIO8_REG input pin status.
Status
Note: status valid only if pin is set to GPI (input) mode.
