i2c communications overview (contd) figure 3 - i2c communication diagram figure 3 illustrates the sequence of signals set by both the host and the sensor for each command. note that for the da - taread command, the host has the option of responding to the second or third bytes of data with a nack instead of ack. this terminates the data transmission after the pressure data, or after the pressure data and upper byte of temperature, have been transmitted. see figure 6 for the i2c timing details. 1. start all ( to wake sensor from sleep mode, zero adc, read temperature and read pressure ) set by bus master: - - - - i st a6 a5 a4 a3 a2 a1 a0 r sp i set by sensor: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - a 2. start pressure ( to wake sensor from sleep mode and read pressure only ) set by bus master: - - - - i st a6 a5 a4 a3 a2 a1 a0 w sp i set by sensor: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - a 3. read data ( with examples of reading pressure, pressure plus 8 bits of temperature and pressure plus 12 bits of temperature ) set by bus master: - - - - i st a6 a5 a4 a3 a2 a1 a0 r a set by sensor ( pressure plus status ): - - - - - - - - - - - - - - - - - - - - a d31 ? d24 d23 ? d16 ?then, one of the following: a) set by bus master, to stop transfer after pressure data received: - - - - - - - - - - - - - - - - - - - - - - - - n sp i --or-- b) set by bus master, to stop transfer after first temperature data byte received: - - - - - - - - - - - - - - a n sp i set by sensor ( high order 8 bits of temperature ): - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - d15 ? d8 --or-- c) set by bus master, to stop transfer after last temperature data byte received: - - - - - - - - - - - - - - a a n sp i set by sensor ( all 12 bits of temperature plus padding bits ): - - - - - - - - - - - - - - - - - - - - - - - - - - - d15 ? d8 d7 ? d0 bus states sensor address data format idle: i a6 ? a0 status: d31 d30 start: st default: 0x28 pressure data: d29 ? d16 stop: sp temperature data: d15 ? d5 ack: a (padding bits:) d4 ? d0 nack: n ?read? bit (1): r ?write? bit (0): w page 8

spi interface spi command sequence dlvr sensors using the spi interface option provide 3 signals for communication: sclk, ss (slave select), and miso. this read-only signaling uses a hardware protocol to control the sensor, difering slightly with the speed/power option selected as described below: fast(f), noise reduced(n) and low-power(l) confgurations: after power-up, the part enters free running mode and begins its periodic conversion cycle, at the interval determined by the programmed power/speed option. this is the simplest confguration. the only bus interaction with the host is the spi dataread opera - tions. polling the sensor at a rate slower than the internal update rate will minimize bus activity and ensure that new values are presented with each transfer. note that the status bits should still be checked to verify updated data and the absence of error conditions. sleep(s) confguration: as with the i2c option, the part enters triggered mode after power-up, and waits for a command from the bus master. to wake the part and start a measurement cycle, the ss pin must be driven low by the host for at least 8usec, then driven high. this can be done by shifting a dummy byte of 8 bits from the sensor. this bus activity can be considered the spi startall command, where the rising edge of ss is the required input to start conversion. updated conversion data is written to the output registers after a period dependent on confguration options ( see performance characteristics). after this update of the registers, the core goes to an inactive (sleep) state. the dataread command simply consists of shifting out 2, 3, or 4 bytes of data from the sensor. the host can check the status bits of the output to verify that new data has been provided. the part remains inactive following this read operation, and another startall operation is needed to wake the part when the next conversion is to be performed. spi bit pattern the sequence of bits and bus signals are shown in the following illustration (figure 4). refer to figure 5 in the interface timing diagram section for detailed timing data. as previously described, the incoming data may be terminated by rais - ing ss after 2, 3, or 4 bytes have been received as illustrated below. figure 4 - spi bit pattern page 10
