7.11.2.1 Features
7.11.2.2 Normal mode
7.11.2.3 Silent mode
7.11.2.4 Undervoltage protection
7.11.2.5 Thermal protection
7.11.2 On-chip, high-speed CAN transceiver
Remark: The on-chip CAN transceiver is available on parts LPC11C22/C24 only.
Compared to the LPC11C12/C14, the LPC11C22/C24 supports fewer GPIO functions,
and in addition, one counter/timer match function is removed to allow interfacing the CAN
high-speed transceiver to the CAN bus. See
A LOW level on pin STB selects Normal mode. In this mode, the transceiver is able to
transmit and receive data via the bus lines CANH and CANL (see
differential receiver converts the analog data on the bus lines into digital data which are
received by the CAN_RXD input of the C_CAN controller.
A HIGH level on pin STB selects Silent mode. In Silent mode the transmitter is disabled,
releasing the bus pins to recessive state. All other functions, including the receiver,
continue to operate as in Normal mode. Silent mode can be used to prevent a faulty
C_CAN controller from disrupting all network communications.

The output drivers are protected against overtemperature conditions. If the virtual junction
temperature exceeds the shutdown junction temperature, T
drivers will be disabled until the virtual junction temperature falls below T
