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 register presets the counter to the value configured by bit TOCC.TOP (TOCC<31:16>) 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 bit TOCC.TOP (TOCC<31:16>). Down-counting is started when the first FIFO element is stored.
