POWER SUPPLY AND FUNCTIONS SIGNALS FOR IF401
POWER SUPPLY
The power supply for the IROl micro-controller, pins 10; 34 and 52, originates in TIMER mode, from regulator IP87 (MC7812 ano ?he 5V regulator incorporated in IP95. In ON mode, it is supplied with powe: irom the UTIMER voltage via the 5V regulator incorporated in IP95.
CLOCK
A 22 MHz VCO/PLL assembly internal to IROl manages the micro-controller. The quartz, QROI ,4 MHz, is used as a reference for the PLL. The components RR95 CR95 and CR97 constitute the loop filter for the PLFl
RESET
CP98, pin 3 of IP95, is the reset capacitor. When ‘bhe voitage at 9 of IP95 reaches 5V and after a delay of a few milliseconds issued my CP98, pin 6 of IP 95 changes from 0 to 5V. Pin 54 of the IROl receives the RESET information.
DETECTION OF MAINS POWER CUT
This circuit is analysed in the power supply chapter.

MEMORIES AND IIC BUS
IR02 MEMORY
IR02 is an EPROM memory with a capacity of 512 Kbytes o’ 4 Mbits. It is the software memory of the IROl and for the default values O! service mode. The lines MMUO to MMU2 are an extension of the address bus.
IR03 MEMORY
II703 is an EEPROM memory, capacity 1 Kbyte or 8 Kbits. It contains the coefficients of service mode, the user adjustments (br;g%ess, contrast, etc.) the synthonised TV channels and if applicable, stand-oy command, etc.
IIC BUS
The IIC bus is charged by pull-up resistors linked to the 5V DC. It is enabled in TIMER and ON modes. It dialogues with or controls the BR03 EEPROM, the tuner, the IF/video/IV01 time bases and the audio processing circuit IS40. Its operating frequency is in the order of 80 KHz. Acknowledgement of receipt of IR03, IV01 and IS40 are taken into account by IROl. In the case of absence of the latter, IROl issues a iaiiure code.
