Interface and control logic
6.1.2.1
Configurable 3-wire or 4-wire interface
The OL2300 can be configured via a simple Serial Peripheral Interface (SPI). The
interface itself can be configured for 3-wire or 4-wire mode. The 4-wire mode uses pin
TEST1 as Serial Data Output SDO when the SDIO is used as input (see
Figure 4
).
EN
pin must be set to enable communication via the 3 or 4-wire serial interface. If the EN
pin is kept low for at least 2
16
XTAL clock pulses, the transmitter device will be reset, the
bit-counter implemented inside the SPI counting the already transferred bits shall be set to
zero, SCK and SDIO are disabled and the device will enter the Power-down mode (also
the crystal oscillator is switched off). If the 4-wire interface has been used, a reset would
also deactivate the SDO pin (set to 3-state; ENSDO is not influenced).
After a transmit command the EN pin has an additional function: At the falling edge of the
EN pin the level of the SDIO pin is latched and directly connected to the modulator input.
In this case it is possible to intercept the RF data transmission without deactivating the PA
and to loop the last transmitted bit while the SDIO interface is used for SFR configuration.
Note that EN must not be low for more than 2
16
XTAL clock pulses otherwise the device
will be reset.
SCK
pin is the clock input for the serial interface. Depending on the start-up condition of
SCK at the rising edge of EN (see
Section 6.7.9
) each rising/falling edge of SCK shifts
data into or gets data from the SPI register set. During RF data transmission the SCK is
don’t care (signal on SCK has no influence on interface).
