The 6 MHz oscillator frequency is multiplied to 48 MHz by an internal PLL.
In the suspend state, the crystal oscillator and the PLL are switched off to save
power. The oscillator operation is controlled by using bit CLKRUN in the Hardware
Configuration register. CLKRUN switches the oscillator on and off.
8.13 Power-on reset
The ISP1183 has an internal power-on reset (POR) circuit. The clock signal normally
requires 3 ms to 4 ms to stabilize.
The triggering voltage of the POR circuit is 0.5 V nominal. A POR is automatically
generated when V
DD(I/O)
goes below the trigger voltage for a duration longer than
50
