I have to interface a MC9S08GB60 to a ADF7021. The ADF7021 has only one pin for the TxRxDATA and one pin for the TxRxClock that specify the data rate. I would like to use the SPI interface of the uC. Could I short circuit the MISO and MOSI pin of the uC and use it as a slave? When the ADF is in transmit mode TxRxData is an input while when it is in receive mode, the TxRxData is an output.
Analog Device suggest
MISO--->|/ |-------- TxRxData
|\ | |
| \| |
do you think it could be work?
thank you in advance
The paint is not clear due to formatting.
if you want, you could see on page 46 of http://www.analog.com/static/imported-files/data_sheets/ADF7021.pdf
don't see SPI mode because there are other problems with the datarata.
If I can't insert extern link, excuse me.
Update: could I use SISO?
