available at the user data interface, D0-D7. The user
optionally compares the received data to the initial
transmitted data for verifying error free operation of
the UART TX/RX circuits.
In this mode, the receiver and transmitter interrupts
are fully operational. The Modem Control Interrupts
are also operational. However, the interrupts can only
be read using lower four bits of the Modem Control
Register (MCR bits 0-3) instead of the four Modem
Status Register bits 4-7. The interrupts are still con-
trolled by the IER.
