10.11 Read cycle
The read cycle is used to read the data values from the internal registers. The I
2
C-bus configuration for a read cycle is shown in Table 13.
The read cycle format is as follows:
1.
The microcontroller begins by asserting a start condition (S).
2.
The first byte (8 bits) contains the device address ‘1001 110’ and the R/W bit is set to logic 0 (write).
3.
The UDA1352HL asserts an acknowledge (A).
4.
The microcontroller writes the 8-bit address (ADDR) of the UDA1352HL register from which data will be read.
5.
The UDA1352HL acknowledges (A) this register address.
6.
The microcontroller generates a repeated start (Sr).
7.
The microcontroller generates the device address ‘1001 110’ again, but this time the R/W bit is set to logic 1 (read).
8.
The UDA1352HL asserts an acknowledge (A).
9.
The UDA1352HL sends two bytes of data with the Most Significant (MS) byte first followed by the Least Significant (LS) byte; after each byte the
microcontroller asserts an acknowledge.
10. After every pair of bytes that are transmitted, the register address is auto incremented; after each byte the microcontroller asserts an acknowledge.
11. The microcontroller stops this cycle by generating a negative acknowledge (NA).
12. The UDA1352HL frees the I
2
C-bus allowing the microcontroller to generate a stop condition (P).
Table 13
Master transmitter reads the UDA1352HL registers in I
2
C-bus mode.
Note
1.
Auto increment of register address.
