Modifications: •Theformat of this data sheet has been redesigned to comply with the new identity guidelines of NXP
Semiconductors.
•Legal texts have been adapted to the new company name where appropriate.
•Descriptivetitle changed from “Fast-mode Plus parallel bus to I2C-bus controller” to “Fm+ parallel bus
to I2C-bus controller”
•Table 12 “I2CCON - Control register (A1= 1, A0= 1) bit description”, description of bit6, 4th
paragraph: changed “... it takes 550µs for the internal oscillator to start up, ...” to “... it takes 550 µs
enable time for the internal oscillator to start up, and the serial interface to initialize.”
•Table 25 “I2C-bus mode selection example[1]”,Table note2: equation denominator close parenthesis
position revised
