ports.
In 2Mhz RC oscillation mode (OSCM2 = “1”, OSCM0 = “X”, OSCM1 = “X”), supply of OSCLK (high-speed
oscillation clock) is started when 2MHz RC oscillation clock pulse count reaches 2048 after oscillation is enabled
(ENOSC is set to “1”).
In 2 MHz RC oscillation mode, both the P10/OSC0 pin and the P11/OSC1 pin can be used as general-purpose input
Figure 6-8 shows the circuit configuration in 2MHz RC oscillation mode.
Notes:
− The 2MHz RC osillation mode can be used within a V
the operation voltage range by using the power supply voltage detection circuit (BLD).
