SCL Line Drive Output Value (SCL_O)
SDA Line Sense Input Value (SDA_I)
SDA Line Drive Output Value (SDA_O)
SPRU760B
In normal functional mode (ST_EN = 0), this bit is don't care. It always reads
0 and a write is ignored.
In system test mode (ST_EN = 1 & TMODE = 11), a 0 forces a low level on the
SCL line, and a 1 puts the I
0: Forces 0 on the SCL data line
-
1: SCL output driver in HiZ state
-
Value after reset is low.
In normal functional mode (ST_EN = 0), this read-only bit always reads 0.
In system test mode (ST_EN = 1 & TMODE = 11), this read-only bit returns the
logical state taken by the SDA line (either 1 or 0).
Value after reset is low.
In normal functional mode (ST_EN = 0), this bit is don't care. It reads as 0 and
a write is ignored.
In system test mode (ST_EN = 1 & TMODE = 11), a 0 forces a low level on the
SDA line and a 1 puts the I
0: Forces 0 on the SDA data line
-
1: SDA output driver in Hi-Z state
-
Value after reset is low.
2
C output driver to a high impedance state.
