NOTE:
Address:
Take these steps to program the mask option register:
SOSCD — Short Oscillator Delay Bit
EPMSEC — EPROM Security Bit
OSCRES — Oscillator Internal Resistor Bit
Program the OSCRES bit to logic 0 in devices using RC oscillators.
Reset:
Read:
Write:
1. Apply the programming voltage, V
2. Write to the MOR.
3. Set the MPGM bit and wait for a time, t
4. Clear the MPGM bit.
5. Reset the MCU.
The SOSCD bit controls the oscillator stabilization counter. The
normal stabilization delay following reset or exit from stop mode is
4064 t
delay.
The EPMSEC bit controls access to the EPROM/OTPROM.
The OSCRES bit enables a 2-M
circuit.
