Bit 1 – TOSKPEN PLCA Transmit Opportunity Skip Enable

When enabled, the device will assert CRS for a number of its assigned PLCA transmit opportunities after transmitting a packet to delay the MAC from transmitting another packet. The number of transmit opportunities skipped before allowing the MAC to transmit is configured in the PLCA Cycle Skip register.

Value	Description
`0`	Transmit opportunity skipping is disabled.
`1`	Transmit opportunity skipping is enabled.
