In the V850ES/JG3, an operating clock that is 4 or 8 times higher than the oscillation frequency output by the PLL
When PLL function is used (×4): Input clock = 2.5 to 5 MHz (output: 10 to 20 MHz)
When PLL function is used (×8): Input clock = 2.5 to 4 MHz (output: 20 to 32 MHz)
Clock-through mode:
(1) PLL control register (PLLCTL)
Cautions 1. When the PLLON bit is cleared to 0, the SELPLL bit is automatically cleared to 0 (clock-
PLL Function
The PLLCTL register is an 8-bit register that controls the PLL function.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 01H.
