EAD MODE
(
ONLY COMMAND REGISTER
)
The read mode of the interface means that the
microcontroller reads data from the PCF8832. To do so,
the microcontroller first sends a command sequence, the
PCF8832 then responds by transmitting data on the
SDO line. After that, SCE is required to go HIGH (see
Fig.39) and this resets the RSTA bit to write operation.
The PCF8832 samples the SDI data at rising edges, but
shifts SDO data at falling SCLK edges. Thus the
microcontroller should read SDO data at rising SCLK
edges.
After the read command sequence has been sent, the
SDI line must be set to 3-state not later than the falling
SCLK edge of the last bit (see Fig.39).
