ST7FLCD1
I²C Single-Master Bus Interface
Bits [5:0] = CC[5:0] 6-bit clock divider.
These bits select the speed of the bus (fSCL) depending on the I²C mode. They are not cleared
when the interface is disabled (PE = 0). The value of the 6-bit clock divider, CC[5:0]
≥ 03h
Fast mode (FM/SM = 0): fSCL > 100 kHz
fSCL = fCPU/([2x([CC5...CC0]+3)]+1)
Standard mode (FM/SM = 1): fSCL ≤100 kHz
fSCL = fCPU/(3x([CC5...CC0]+3))
Note:
The programmed fSCL speed assumes that there is no load on the SCL and SDA lines.
I²C DATA REGISTER (I2CDR)
Read / Write
Reset Value: 0000 0000 (00h)
Bits [7:0] = D[7:0] 8-bit Data Register.
These bits contain the byte to be received or transmitted on the bus.
Transmitter mode: Bytes are automatically transmitted when the software writes to the DR
register.
Receiver mode: The first data byte is automatically received in the DR register using the least
significant bit of the address.
Then, the subsequent data bytes are received one-by-one after reading the DR register.
