2.8 Mask Option Register
The mask option register (MOR) is an EPROM/OTPROM byte that controls the following options:
COP watchdog (enable or disable)
External interrupt pin triggering (edge-sensitive only or edge- and level-sensitive)
Port A external interrupts (enable or disable)
Port pulldown resistors (enable or disable)
STOP instruction (stop mode or halt mode)
Crystal oscillator internal resistor (enable or disable)
EPROM security (enable or disable)
Short oscillator delay (enable or disable)
Take the following steps to program the mask option register (MOR):
1.
Apply the programming voltage, V
PP
, to the IRQ/V
PP
pin.
2.
Write to the MOR.
3.
Set the MPGM bit and wait for a time, t
MPGM
.
4.
Clear the MPGM bit.
5.
Reset the MCU.
SOSCD — Short Oscillator Delay Bit
The SOSCD bit controls the oscillator stabilization counter. The normal stabilization delay following
reset or exit from stop mode is 4064 t
cyc
. Setting SOSCD enables a 128 t
cyc
stabilization delay.
1 = Short oscillator delay enabled
0 = Short oscillator delay disabled
EPMSEC — EPROM Security Bit
The EPMSEC bit controls access to the EPROM/OTPROM.
1 = External access to EPROM/OTPROM denied
0 = External access to EPROM/OTPROM not denied
OSCRES — Oscillator Internal Resistor Bit
The OSCRES bit enables a 2-M
internal resistor in the oscillator circuit.
1 = Oscillator internal resistor enabled
0 = Oscillator internal resistor disabled
NOTE
Program the OSCRES bit to logic 0 in devices using low-speed crystal or
RC oscillators with external resistor.
