Question

Below you find a timing diagram for an 12C communication stream. Please an following What slave address (7-bit) is being talked to? (Do not include the read/write bit) b. Is the master going to read or write to the slave? c. After the address is transmitted, how many bytes are transmitted? d. What is the value of those byte(s) SDA unnen sa um mns

Answer 1

1 In 12€ Protocol The Data frame will be as Read/write Ist For lo bit de les con partie la bite slave IR for 10 bit address TAG Ank to Start slave Address bir .. Acknadedgement or No Ack . stop bir Here we are given that it is a bit slave - address Read/write operation = 1 . Reald phead/write so write Start bit is a SPA must have transition from high to low when Set is high then START bit

indicated lie start of data transmission) ACKYNACK to i bit in size: i fis gik bit of all it is a bit after i Byte (8 bits) are transmitted indicates whether there is a need for retransmission from Moster if ACK=0 then No need for retransmission NACK if ACK SNACK = 1 then then ! the NACIO there is a need forta retransmission

Now given . and one thing in Ize protocol Communication data on SDA is stable positive level of SCAL where data changes com framsi Hons take place Loh on Low level of SCAL 'So. Now data transmitted by given timing diagram START bir SDA DO 10100100111100! ACK 0 10 100 V . Slave Address 1 . Read/write 8bit data (byte) The data is taken into consideration on High a level of see Аска SAA D100 170.0000 NACK sbit data (1 byte)

la Slave address = ololool - Since that is the data after START bit. b) . Read/Write bit = 0 S that indicates Master wants to write data (send data) to share & After the address of Slave and ACKINACK neglecting the ACKNACK of the bytes received the state or Master transmitted 2 bytes Those too bytes are transmitted by Masters i byte = 1!1100!! :(F3), 2 byte - 10010000 =(90),

A The data transmitted to slave' The 1st transmitted" byte receives a ACK (0) from slave . 2nd transmitted by te received on NACKCI) from slave Tie Slave writes on SDA after every byte transfer of data
