We are using the CYBLE-214015-01 with the impediment, that only the pin P0.7 has the capability of SWDCLK and SCB0_SCLK. So we cant debug and access the SPI at the same time. Is there a similar SOC with similar power consumption an features with SWDCLK and SCB0_SCLK on different pins?

Hi,

The CYBLE-214015-01 module has few pins accessible to the user. In those pins P1[7] and P1[6] are not available. So the users cannot be able to use the SCB as SPI on these pins.

So we recommend you to use PSoC 4 BLE silicon instead of CYBLE-214015-01 module where all the pins are exposed to user. Please note that when you select PSoC 4 BLE silicon you should connect all other circuitry and antenna also.

Please refer the following datasheet.

Hope this information helps.

Thanks

Hi,

It says in PSoC Creator 4.4 under [Design Wide Resources > System] that

"Controls whether or not to reserve pins for debugging. If SWD is selected, the debugging features of the chip will be externally accessible. If GPIO is selected the pins are available for general purpose use. When set to GPIO the device can still be acquired with SWD, and reprogrammed, but not for debugging."

Does this mean that I can still program my CYBLE-214015-01 module with the P0[7] and P0[6] and subsequently use the SCB as SPI on these pins?
