Structure of Register The figure of each register structure describes its functions, contents at reset, and attributes as follows: b7 b6 b5 b4 b3 b2 b1 b0 Fix these bits to “0.” Stack page selection bit Nothing is allocated for this bit. This is write enabled bit and is undefined at reading. XCOUT drive capacity selection bit Main clock (XIN–XOUT) stop bit Internal system clock selection bit P50, P51/XCIN, XCOUT selection bit 0: In page 0 area 1: In page 1 area 0: Low 1: High 0: Oscillates 1: Stops 0: XIN–XOUT selected (Ordinary mode) 1: XCIN–XCOUT selected (low-speed mode) 0: P50, P51 1: XCIN, XCOUT Name Function At reset B RW 0, 1 2 3 4 5 6 7 0 0 ? 0 0 0 0 ? !
