13.3.1.7 Standard Speed Clock SCL Low Count
(IC_SS_SCL_LCNT)
Sets the SCL clock low-period count for standard speed (SS). Can be written only
when the I2C is disabled (IC_ENABLE==0). Writes at other times have no effect.
MEM Offset () 0B0002818h
Security_PolicyGroup
IntelRsvd False
Size 32 bits
Default 0000_01D6h
Bits Access
Type
Default Description PowerWell ResetSignal
31:16 RO 16'b0 Reserved (RSV)
15:0 RW 16'h01d6 SS SCL clock low-period
count (IC_SS_SCL_LCNT)
Must be set before any I2C
bus transaction can take
place to ensure proper I/O
timing.
The minimum valid value is
8; hardware prevents values
less than this being written,
and if attempted results in 8
being set.
13.3.1.8 Fast Speed Clock SCL High Count (IC_FS_SCL_HCNT)
Sets the SCL clock high-period count for fast speed (FS). Can be written only when
the I2C is disabled (IC_ENABLE==0). Writes at other times have no effect.
MEM Offset () 0B000281Ch

15:0 RW 16'h003c FS SCL clock high-period
count (IC_FS_SCL_HCNT)
Must be set before any I2C
bus transaction can take
place to ensure proper I/O
timing.
