33 /* Default Guard Time of 250µs until interface capability register is read */
37 /* Guard Time of 250µs after I2C slave NACK */
41 /* Guard Time bit masks; SR is repeated start, RW is read then write, etc. */
277 * Guard Time:
282 * Before the Guard Time is read (or after the TPM failed to send an I2C NACK),
283 * a Guard Time of 250µs applies.
285 * Various flags in the same register indicate if a guard time is needed:
286 * - SR: <I2C read with repeated start> <guard time> <I2C read>
287 * - RR: <I2C read> <guard time> <I2C read>
288 * - RW: <I2C read> <guard time> <I2C write>
289 * - WR: <I2C write> <guard time> <I2C read>
290 * - WW: <I2C write> <guard time> <I2C write>
