10.4.6 Transmit Manual Error Insertion

Transmit errors can be inserted in some of the functional blocks. These errors can be inserted using register bits in

the functional blocks, using the global GL.CR1.TMEI bit, using the port PORT.CR1.TMEI bit, or by using the GPIO6

pin configured for TMEI mode.

There is a transmit error insertion register in the functional blocks that allow error insertion. The MEIMS bit controls

whether the error is inserted using the bits in the error insertion register or using error insertion signals external to

that block. When bit MEIMS=0, errors are inserted using other bits in the transmit error insertion register. When bit

MEIMS=1, errors are inserted using a signal generated in the port or global control registers or using the external

GPIO6 pin configured for TMEI operation.
