179 / 296 page  Page 163 TMP86FS49AIUG (2) External clock When an external clock is selected by setting SIO1CR<SCK> to “111B”, the clock via the SCK1 pin from an external source is used as the serial clock. To ensure shift operation, the serial clock pulse width must be 4/fc or more for both “H” and “L” levels. Figure 14-3 External Clock 14.3.1.2 Shift edge The leading edge is used to transmit data, and the trailing edge is used to receive data. (1) Leading edge shift Data is shifted on the leading edge of the serial clock (falling edge of the SCK1 pin input/output). (2) Trailing edge shift Data is shifted on the trailing edge of the serial clock (rising edge of the SCK1 pin input/output).
