RL78/G13 CHAPTER 5 CLOCK GENERATOR
R01UH0146EJ0100 Rev.1.00 290
Sep 22, 2011
Cautions 1. Be sure to set bit 3 to 0 to 0.
2. The clock set by the CSS bit is supplied to the CPU and peripheral hardware. If the
CPU clock is changed, therefore, the clock supplied to peripheral hardware (except
the real-time clock, interval timer, clock output/buzzer output, and watchdog timer) is
also changed at the same time. Consequently, stop each peripheral function when
changing the CPU/peripheral hardware clock.
3. If the subsystem clock is used as the peripheral hardware clock, the operations of
the A/D converter and IICA are not guaranteed. For the operating characteristics of
the peripheral hardware, refer to the chapters describing the various peripheral
hardware as well as CHAPTER 29 ELECTRICAL SPECIFICATIONS.
