Bits 31:16 – TOP[15:0] Timeout Period

Start value of the Timeout Counter (down-counter). Configures the Timeout Period.

Bits 2:1 – TOS[1:0] Timeout Select

When operating in Continuous mode, a write to TOCV presets the counter to the value configured by TOCC.TOP and continues down-counting. When the Timeout Counter is controlled by one of the FIFOs, an empty FIFO presets the counter to the value configured by TOCC.TOP. Down-counting is started when the first FIFO element is stored.

Value	Name	Description
0x0	CONT	Continuous operation.
0x1	TXEF	Timeout controlled by TX Event FIFO.
0x2	RXF0	Timeout controlled by Rx FIFO 0.
0x3	RXF1	Timeout controlled by Rx FIFO 1.

Bit 0 – ETOC Enable Timeout Counter

Value	Description
0	Timeout Counter disabled.
1	Timeout Counter enabled.
