C-bus controller” to “Fm+ parallel bus

to I

C-bus controller”

• Table 12 “I2CCON - Control register (A1 = 1, A0 = 1) bit description”, description of bit 6, 4

paragraph: changed “... it takes 550 µs 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 “I
