17.1.1.1 CLK Polarity
As shown in figure 17.14, the CKPOL bit in the UiC0 register (i = 0 to 4) determines the polarity of the serial
clock.
(1) When the CKPOL bit in the UiC0 register (i = 0 to 4) is set to 0 (transmit data output at the
(2) When the CKPOL bit is set to 1 (transmit data output at the rising edge and receive data input
The above applies under the following conditions:
NOTES:
falling edge and receive data input at the rising edge of the serial clock )
at the falling edge of the serial clock)
- UFORM bit in the UiC0 register is set to 0 (LSB first)
- UiLCH bit in the UiC1 register is set to 0 (not inverted).
1. The CLKi pin output level is "H" when no transmit and receive operation is in progress.
2. The CLKi pin output level is "L" when no transmit and receive operation is in progress.
