Description
Transmit End Interrupt Enable
When this bit is set to 1, TEI interrupt request is enabled.
Clock Enable 1 and 0
Selects the clock source and SCK pin function.
Asynchronous mode:
00: Internal clock, SCK pin used for input pin (input signal
is ignored) or output pin (output level is undefined)
01: Internal clock, SCK pin used for clock output (The
output clock frequency is the same as the bit rate)
10: External clock, SCK pin used for clock input (The
input clock frequency is 16 times the bit rate)
11: External clock, SCK pin used for clock input (The
input clock frequency is 16 times the bit rate)
Clocked synchronous mode:
00: Internal clock, SCK pin used for synchronous clock
output
01: Internal clock, SCK pin used for synchronous clock
output
10: External clock, SCK pin used for synchronous clock
input
11: External clock, SCK pin used for synchronous clock
input
