Function
LBI Interrupt Input from Peripheral 1
LBI Clock Output
This is signal provides the internal LBI clock
which is frequency of signal CLK divided by n
(n must be configured with bit field
GMODE.LCD(1:0)).
LCLK is provided for connection of
synchronous peripherals.
Note: The duty cycle (high to low in %) of
Function
Receive Clock
The function of these pins depends on the
selected clock mode.
In each channel, RxCLKn may supply either
– the receive clock (clock mode 0, 4), or
– the receive and transmit clock (clock mode
– the clock input for the baud rate generator
Receive Data
Serial data is received on these pins.

(clock mode 2, 3).
LCLK depends on the clock division
factor:
n = 2: 25%
n = 4: 12.5%
n = 16: 3.125%
The high phase is always T
typically 15ns at 33 MHz system clock
frequency.
