PCF8833

When sending commands to the PCF8833 the D/C line

must be pulled HIGH when the command data is

transferred (see Fig.38). The same is valid when RAM

data is sent to the PCF8833 (see Fig.39).

The PCF8833 can send data back to the microcontroller in

2 different ways. The protocol for the RDID1, RDID2,

RDID3 and RDTEMP commands is illustrated in Fig.40.

Descriptions of these commands is given in Chapter 6.

When reading out RDTEMP it is recommended to read this

data several times to validate the readout number.

When using the RDDIDIF (see Section 6.2.6) or RDDST

(see Section 6.2.7) commands the PCF8833 sends

24 or 32 data bits respectively back to the microcontroller.

The protocol for the RDDIDIF and RDDST commands is

illustrated in Fig.41.

The parallel interface timing diagram is illustrated in

Fig.52. For the dummy read cycle the time tACC is

referenced to the rising edge of the RD signal.
