Read / Write
Reset Value: 0000 0000 (00h)
Bit 7:6 = Reserved. Forced to 0 by hardware.
Bit 5 = PE Peripheral enable.
This bit is set and cleared by software.
0: Peripheral disabled
1: Master/Slave capability
Notes:
– When PE=0, all the bits of the CR register and
– When PE=1, the corresponding I/O pins are se-

Bit 4 = ENGC Enable General Call.
This bit is set and cleared by software. It is also
cleared by hardware when the interface is disa-
bled (PE=0). The 00h General Call address is ac-
knowledged (01h ignored).
0: General Call disabled
1: General Call enabled
Note: In accordance with the I2C standard, when
GCAL addressing is enabled, an I2C slave can
only receive data. It will not transmit data to the
master.
Bit 3 = START Generation of a Start condition.
This bit is set and cleared by software. It is also
cleared by hardware when the interface is disa-
bled (PE=0) or when the Start condition is sent
(with interrupt generation if ITE=1).

Bit 2 = ACK Acknowledge enable.
This bit is set and cleared by software. It is also
cleared by hardware when the interface is disa-

Bit 1 = STOP Generation of a Stop condition.
This bit is set and cleared by software. It is also
cleared by hardware in master mode. Note: This
bit is not cleared when the interface is disabled
(PE=0).

– In slave mode:
Bit 0 = ITE Interrupt enable.
This bit is set and cleared by software and cleared
by hardware when the interface is disabled
(PE=0).

0: No start generation
1: Start generation when the bus is free
0: No stop generation
1: Stop generation after the current byte transfer
or after the current Start condition is sent. The
STOP bit is cleared by hardware when the Stop
condition is sent.
0: No stop generation
1: Release the SCL and SDA lines after the cur-
rent byte transfer (BTF=1). In this mode the
STOP bit has to be cleared by software.
