Byte Data Link Communications (BDLC)
15.9.7 Port DLC Data Register
Read: Anytime
Write: Anytime
This register holds data to be driven out on port DLC pins or data received from port DLC pins.
When configured as an input, a read returns the pin level. When configured as output, a read returns the
latched output data.
Writes do not change pin state when the pins are configured for BDLC output. Upon reset, pins are
configured for general-purpose high impedance inputs.
