28.6
The baud rate generator for external clock (hereafter abbreviated as BRG) is included in the
SCIF/IrDA and supplies the IrDA block with a sampling clock (BRGCLK), which is derived from
the external clock (SCIF_CLK) or internal clock (Pck0) divided by the division ratio from 1
through 2 to the sixteenth power minus 1.
