Serial I/O
SCLKI0/
SCLKO0
UART transmit/receive Input/output When channel 0 is in UART mode:
clock output or CSIO
transmit/receive clock
input/output
This pin outputs a clock derived from BRG output by
dividing it by 2.
When channel 0 is in CSIO mode:
This pin accepts as input a transmit/receive clock when
external clock is selected or outputs a transmit/receive
clock when internal clock is selected.
SCLKI1/
SCLKO1
UART transmit/receive Input/output When channel 1 is in UART mode:
clock output or CSIO
transmit/receive clock
input/output
This pin outputs a clock derived from BRG output by
dividing it by 2.
When channel 1 is in CSIO mode:
This pin accepts as input a transmit/receive clock when
external clock is selected or outputs a transmit/receive
clock when internal clock is selected.
SCLKI4/
SCLKO4
UART transmit/receive Input/output When channel 4 is in UART mode:
clock output or CSIO
transmit/receive clock
input/output
This pin outputs a clock derived from BRG output by
dividing it by 2.
When channel 4 is in CSIO mode:
This pin accepts as input a transmit/receive clock when
external clock is selected or outputs a transmit/receive
clock when internal clock is selected.
SCLKI5/
SCLKO5
UART transmit/receive Input/output When channel 5 is in UART mode:
clock output or CSIO
transmit/receive clock
input/output
This pin outputs a clock derived from BRG output by
dividing it by 2.
When channel 5 is in CSIO mode:
This pin accepts as input a transmit/receive clock when
external clock is selected or outputs a transmit/receive
clock when internal clock is selected.
