the resynchronization circuitry activity and will not
affect operation since the bit cell period at 128 kb/s
and 256 kb/s is relatively large. There is a one frame
delay through the FDI circuit for asynchronous
operation. Refer to the specifications of Figures 12
& 13 for both synchronous and asynchronous SSI
timing.
PWRST/Software Reset (Rst)
While the MT91L60 is held in PWRST no device
control or functionality is possible. While in software
reset (Rst=1, address 03h) only the microport is
functional. Software reset can only be removed by
writing Rst logic low or by setting the PWRST pin.
After Power-up reset (PWRST) or software reset
(Rst) all control bits assume their default states;

2048 kb/s operation with Dout tri-stated while there
is no strobe active on STB. If a valid strobe is
supplied to STB, then Dout will be active, during the
defined channel.
To attain complete power-down from a normal
operating condition, write PDFDI = 1 and PDDR = 1
(Control Register 1, address 03h) or put PWRST pin
low.
