TWIM and TWIS user interface registers. Please refer to the TWIM and TWIS sections for more
information.
Notes:
1. Standard mode:
; fast mode:
.
2. A device must internally provide a hold time of at least 300 ns for TWD with reference to the falling edge of TWCK.
Notations:
C
b = total capacitance of one bus line in pF
tclkpb = period of TWI peripheral bus clock
tprescaled = period of TWI internal prescaled clock (see chapters on TWIM and TWIS)
The maximum tHD;DAT has only to be met if the device does not stretch the LOW period (tLOW-I2C) of TWCK.
