Note 1: Transfer rates in I/O interface mode are 8 times faster than the values given in the

above table.

Note 2: This table is calculated for when fc is selected as the system clock, the clock gear is set

to fc, and the system clock is selected as the prescaler clock input.

How to calculate the transfer rate (when timer 0 is used):

Clock frequency selected by SYSCR0<PRCK1:0>

Transfer rate

TREG0 × 8 × 16

(when timer 0 (Input clock φT1) is used)

Note 1: Timer 0 match detect signal cannot be used as the transfer clock in I/O interface mode.

Note 2: This table is calculated for when fc is selected as the system clock, the clock gear is set

to fc, and fFPH is selected as the prescaler clock input.
