I2C clock control register (CCR)
Reset value: 0000 0000 (00h)
Bit 7 = FM/SM Fast/Standard I2C mode.
This bit is set and cleared by software. It is not cleared when the interface is disabled
(PE=0).
0: Standard I2C mode
1: Fast I2C mode
Bit 6:0 = CC[6:0] 7-bit clock divider.
These bits select the speed of the bus (FSCL) depending on the I
2C mode. They are not
cleared when the interface is disabled (PE=0).
Refer to Section 13: Electrical characteristics for the table of values.
Note:
The programmed fSCL assumes no load on SCL and SDA lines.
