Figure 6.1
Figure 6.2
The supply voltage for internal logic is generated by reducing the input voltage from the VCC pin with the
voltage regulators. Figure 6.1 shows a block diagram of the voltage regulators for internal logic, and
Figure 6.2 shows the VRCR register.

Notes:
Voltage Regulators for Internal Logic
1. Set the PRC31 bit in the PRCR3 register to 1 (write enabled) before rewriting this register.
2. This bit is fixed to 0 if the CM05 bit in the CM0 register is 0 (main clock oscillator enabled) or the CM10 bit in
3. While the main regulator is stopped, do not rewrite the flash memory.
the CM1 register is 0 (PLL oscillator enabled) .
