Address Register (S2ADR)
This 8-bit register may be loaded with the 7-bit
slave address to which the controller will respond
when programmed as a slave receive/transmitter.
The Start/Stop Hold Time Detection and System
Clock registers (Tables
57
and
58
) are included in
the I
2
C unit to specify the start/stop detection time
to work with the large range of MCU frequency val-
ues supported. For example, with a system clock
of 40MHz.

Note: SLA6 to SLA0: Own slave address.
