The firmware of the PIC16C765 (3)

• ConfiguredUSB: (macro) blocks the firmware execution by polling bits of the status register, until the I/O device has been configured

• PutEP1:sends data to the host through endpoint 1. This function receives as parameters the address of the data block (indirect addressing by means of registers FSR/IRP), and the block size (register W). If the function succeeds, it sets the Carry Flag in the status register and it returns in W the number of bytes copied in the transmission buffer
