(5) System clock control register (CKC)
R01UH0004EJ0401 Rev.4.01
Jul 2, 2010
This register is used to select a CPU/peripheral hardware clock and a division ratio.
CKC can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 09H.
Address: FFFA4H
Symbol
