Notes on Serial Input:
Figure 4.4 Timing of the serial input/output
*External clock (SCK) input at the system clock falling edge in the middle of the T2 state is taken in the
evaluation MCU at the system clock rising edge in the beginning of the T3 state. And serial data input (SIN) is
taken in the evaluation MCU in the first half of the T2 state.
In this product, when the external clock (SCK) is used for the serial interface synchronous clock, the operation
timing of the SCK pin is different from that of an actual MCU because the SCK pin is the emulation port.
Figure 4.4 shows that the operation timing when the external clock (SCK) is used for the serial interface
synchronous clock.
Therefore, in this product, the serial I/O external input frequency, f(SCK) is limited to the maximum value
shown below:
f(SCK): f(STCK)/6 x 0.9(Max)[Hz]
Make sure that the set timing of the serial interface transmit/receive completion flag (SIOF) is also different.
