12 RW 1'b0 IC_10BITADDR_MASTER
(IC_10BITADDR_MASTER
)
This bit controls whether the
I2C controller starts its
transfers in 7-or
10-bit addressing mode
when acting as a master.
0: 7-bit addressing
1: 10-bit addressing
11 RW 1'b0 Special Command Enable
(SPECIAL)
This bit indicates whether
software performs a General
Call or START BYTE
command.
0: ignore bit 10
GC_OR_START and use
IC_TAR normally
1: perform special I2C
command as specified in
GC_OR_START field
10 RW 1'b0 Special Command Type
(GC_OR_START)
If IC_TAR bit 11 (SPECIAL)
is set to 1, then this bit
indicates whether a General
Call or START byte
command is to be performed
by the I2C Controller.
0: General Call Address after
issuing a General Call, only
writes may be performed.
Attempting to issue a read
command results in setting
bit 6 (TX_ABRT) of the
IC_RAW_INTR_STAT
register. I2C controller
remains in General Call
mode until the SPECIAL bit
value (bit 11) is cleared.
1: START BYTE
9:0 RW 10'h055 Master Target Address
(IC_TAR)
