11.1
11.1.1
The SH7727 has an on-chip USB interface (USB) which requires a fixed 48-MHz clock source.
The extend clock pulse generator (EXCPG) generates a divided clock from the internal clock (Iφ),
the bus clock (Bφ), or the external clock (UCLK).
Because the clock sources, which can be a candidate to be used by EXCPG, vary from CPG
setting or external clock source, user of SH7727 must adjust the divided clock, carefully to be 48
MHz.
