Electrical Characteristics
4.3.6
The AUDMUX provides a programmable interconnect logic for voice, audio and data routing between
internal serial interfaces (SSI) and external serial interfaces (audio and voice codecs). The AC timing of
AUDMUX external pins is hence governed by the SSI module. Please refer to their respective electrical
specifications.
4.3.7
This section describes the electrical information of the CSPI.

depict the master mode and slave mode timings of CSPI, and
trfs = 1.6 * T + tsui + tco + tbuf + tbuf
tdzfs = time_dzfs * T - (tskew1)
tss = time_ss * T - (tskew1 + tskew2)
tdzfs_mli =max (time_dzfs, time_mli) * T - (tskew1 + tskew2)
tli1 > 0

tcvh = (time_cvh *T) - (tskew1 + tskew2)
ton = time_on * T - tskew1
toff = time_off * T - tskew1
