We are using the RCM5700 module and We would want to use the serial port E as sync. The pinout definitions is as follow:
*PE6 as TXE
*PC4 as TCLKE
*PE5 as RCLKE
*PE7 as RXE
TXE is an output and RXE is an input.
When in our device we are talking about internal clock, TCLKE & RCLKE are outputs and the clock is generated by Rabbit timers. But with external clock, could be some of next two configurations:
*TCLKE & RCLKE external. The RCM will receive the clock
*RCLK external and TCLKE internal (generated by Rabbit)
Is that posssible these configuration?
How would it be do?
When on the register SECR we configure as external clock (bits 3:2->10), are TCLKE & RCLKE inputs?
