I2C Single-Master Bus Interface
ST7FLCD1

generation if ITE = 1. It is cleared by software by reading the SR register followed by a read or write
of DR register. It is also cleared by hardware when the interface is disabled (PE = 0).
Following a byte transmission, this bit is set after reception of the acknowledge clock pulse. In case
an address byte is sent, this bit is set only after the EV2 event (See
Section 10.5: Transfer
Sequencing
). BTF is cleared by reading SR register followed by writing the next byte in DR register.
Following a byte reception, this bit is set after transmission of the acknowledge clock pulse if
ACK = 1. BTF is cleared by reading SR register followed by reading the byte from DR register.
The SCL line is held low when BTF = 1.
0
Byte transfer not done
1
Byte transfer succeeded
Bit 2 = Reserved.
Forced to 0 by hardware
.
Bit 1 = M/IDL
Master/Idle.
This bit is set by hardware when the interface is in Master mode (writing START = 1). It is cleared by
hardware after a Stop condition on the bus. It is also cleared by hardware when the interface is
disabled (PE = 0).
0
Idle mode
1
Master mode
Bit 0 = SB
Start bit.
This bit is set by hardware when a Start condition is generated (following a write START = 1). An
interrupt is generated if ITE = 1. It is cleared by software by reading the SR register followed by
writing the address byte in DR register.
It is also cleared by hardware when the interface is disabled
(PE = 0).
0
No Start condition
1
Start condition generated
I2C CLOCK CONTROL REGISTER (I2CCCR)
Read / Write
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
Fast I2C mode
1
Standard I2C mode
Bit 6 = FILTOFF
Filter Off.
This bit is set and cleared by software, it is not taken into account in the EMU version and is
considered as always set to 1 (inactive filter).
When set, it disables the filter of the I2C pads in order to achieve speeds of over 400 kHz on a short-
length I2C bus (at the user’s responsibility). Such high frequencies are computed with the Fast mode
formula given below.
