INTRODUCTION
There are eleven overlay registers (OR0 through OR9 and OR15) in the MC145574. The overlay regis-
ters are a second bank of registers available when the overlay register control bit BR15(7) is set to
a logic 1. These overlay registers are in the IDL2 TSA mode used to assign the timeslot used by each
channel (B1, B2, and D) for transmission and reception; OR0 through OR5, OR6, OR7, and OR8
are control registers used in the GCI indirect mode, and OR15 gives the revision number of the S/T
chip.
