If the SJA1000 is in the sleep mode a recessive level is output on the TX0 and TX1 pins with respect to the contents
within the output control register. If the SJA1000 is in the reset state (reset request = HIGH) or the external reset pin RST
is pulled LOW the outputs TX0 and TX1 are floating.
The transmit output stage is able to operate in different modes. Table 47 shows the output control register settings.
Table 47 Interpretation of OCMODE bits
Note
1. In test output mode TXn will reflect the bit, detected on RX pins, with the next positive edge of the system clock.
6.5.3.1
In normal output mode the bit sequence (TXD) is sent via TX0 and TX1. The voltage levels on the output driver pins TX0
and TX1 depend on both the driver characteristic programmed by OCTPx, OCTNx (float, pull-up, pull-down, push-pull)
and the output polarity programmed by OCPOLx.
