ATA6562/3

To switch the device in normal operating mode, set the

STBY pin to low and the TXD pin to high (see Table 1-1

and Figure 1-2). The STBY pin provides a pull-up

resistor to VIO, thus ensuring a defined level if the pin

is open.

1.1.1

NORMAL MODE

A low level on the STBY pin together with a high level

on pin TXD selects the Normal mode. In this mode, the

transceiver is able to transmit and receive data via the

CANH and CANL bus lines (see Functional Block

Diagram). The output driver stage is active and drives

data from the TXD input to the CAN bus. The

High-Speed Comparator (HSC) converts the analog

data on the bus lines into digital data which is output to

pin RXD. The bus biasing is set to V_VCC/2 and the

undervoltage monitoring of VCC is active.

Please note that the device cannot enter Normal mode

as long as TXD is at ground level.

The switching into Normal mode is depicted in the

following two figures, Figure 1-2 and Figure 1-3.

The slope of the output signals on the bus lines is

controlled and optimized in a way that guarantees the

lowest possible electromagnetic emission (EME).
