| CLHR | Clock Low High Ratio 0 (STANDARD): The ratio between low period and high period counters (Nlow:Nhigh) is 4:4 1 (ASYMMETRIC): The ratio between low period and high period counters (Nlow:Nhigh) is 6:3 2 (FAST): The ratio between low period and high period counters (Nlow:Nhigh) is 11:6 | 
| BITO | Bus Idle Timeout 0 (OFF): Timeout disabled 1 (40PCC): Timeout after 40 prescaled clock cycles. In standard mode at 100 kHz, this results in a 50us timeout. 2 (80PCC): Timeout after 80 prescaled clock cycles. In standard mode at 100 kHz, this results in a 100us timeout. 3 (160PCC): Timeout after 160 prescaled clock cycles. In standard mode at 100 kHz, this results in a 200us timeout. |
