Abstract: A serial transmission peripheral device for transmitting serial transmission data with a variable data length includes a pulse forming unit; and a register programmable to set a desired transmission length. The peripheral device is operable to determine an actual transmission length and calculate a length of a pause pulse and to add the pause pulse at the end of a transmission to generate a transmission having a constant length.

Abstract: A system for determining a unit time of a serial transmission protocol, wherein the serial transmission protocol defines a unit time (UT) by transmitting a calibration pulse having a predetermined length of N*UT and wherein a receiver is operated by system clock, includes: a clock divider for dividing the system clock by M, wherein M evenly divides N, and a detector for sampling a received data nibble length by using a dithered sampling clock.
