Thursday, September 29, 1: Here is the call graph for this function:. Set to zero, if no bytes are expected from the slave device. Even though it violates the minimum PLL input and for that matter, the minimum output?

Interrupt mask register address. Internal device address size mask. Slave address of the destination. Basically you power-up the device with TST pulled high the other pins have internal pull-ups so no need to explicitly pull them highwait for about 10 seconds and then power-up the device without TST pulled high. This slave address must be specified as a 7-bit address. Maximum number of bytes to receive. Thursday, September 29, 7: Internal address register offset. Now the problem is fixed and the code works perfect!
