L138 McASP Sample Edge configuration

Hi

I am connecting my L138 McASP to a Bluetooth chip.

I am trying to confirm the correct configuration to use in regards to which clock edge is data being latched into L138 and data driven from L138.

Here are my McASP settings.

 

CLKXP = 0 (L138 shifts data on rising edge)

ASYNC = 0 (Synchronous)

CLKXM = 1 (Internal transmit clock source)

CLKDIV = 0 (/1)

 

CLKRP = 0 (don't care since ASYNC=0)

CLKRM = 0 (don't care since ASYNC=0)

CLKDIV = 0 (don't care since ASYNC=0)

 

Based on this setting, data going out of L138 will be driven on the rising edge, and sampled on the falling edge at the Bluetooth chip.

Can somebody confirm the edge that L138 is expecting to latch & sample at for data input from the Bluetooth chip?
