i = 0 to 4
fEXT = external clock frequency
The above applies under the following conditions:
NOTE:
- UiMR register: CKDIR bit = 1 (external clock)
- UiC0 reigster: CRD bit = 1 (CTS function disabled)
1. Satisfy the following conditions, while the CLKi pin input is "H" before the data receive operation.
(1)
- UiC1 register: TE bit = 1 (transmit operation enabled)
- Write dummy data to the UiTB register
