|R/W||0x1||Remote Ack SDA Output Setup. |
When a Control Channel (remote) access is active, this field configures setup time from the SDA output relative to the rising edge of SCL during ACK cycles.
Setting this value increases setup time in units of 640 ns. The nominal output setup time value for SDA to SCL when this field is 0 is 80 ns.
|3:2||SDA_OUTPUT_DELAY||R/W||0x0||SDA Output Delay. |
This field configures additional delay on the SDA output relative to the falling edge of SCL. Setting this value increases output delay in units of 40 ns.
Nominal output delay values for SCL to SDA are:
00 : 240 ns
01: 280 ns
10: 320 ns
11: 360 ns
|R/W||0x0||Speed up I2C Bus Watchdog Timer.|
1: Watchdog Timer expires after approximately 50 microseconds
0: Watchdog Timer expires after approximately 1 second.
|R/W||0x0||Disable I2C Bus Watchdog Timer. |
When the I2C Bus Watchdog Timer may be used to detect when the I2C bus is free or hung up following an invalid termination of a transaction. If SDA is high and no signalling occurs for approximately 1 second, the I2C bus is assumed free. If SDA is low and no signaling occurs, the device attempts to clear the bus by driving 9 clocks on SCL.
