6 / 36 page July 1994 6 Philips Semiconductors Preliminary specification Programmable deflection controller TDA9151B I2C-bus commands Slave address: 8C HEX = 1000110X BIN READ MODE The format of the status byte is: PON PROT 000000 Where: PON is the status bit for power-on reset (POR) and after power failure: • Logic 1: – after the first POR and after power failure; also set to 1 after a severe voltage dip that may have disturbed the various settings – POR 1 to 0 transition, VCC = 6.25 V (typ.) – POR 0 to 1 transition, VCC = 5.75 V (typ.) • Logic 0: – after a successful read of the status byte. PROT is the over voltage detection for the scaled EHT input: • Logic 1: – if the scaled EHT rises above the reference value of 3.9 V • Logic 0: – after a successful read of the status byte and EHT <3.9 V. Remark: a read action is considered successful when an End Of Data signal has been detected (i.e. no master acknowledge). Table 1 Write mode with auto increment; subaddress and data byte format. Notes 1. X = don’t care. 2. Data bit used in another function.
