Mask Option Register (MOR)
The Mask Option Register (MOR) contains programmable EPROM bits to control mask options,
and cannot be changed in User mode. The erased state are zeros. This register is latched upon
reset going away.
SMD — SLOW Mode at Power-on
When programmed to “1”, this bit enables SLOW mode at power-up. Operating frequency,
fOP=fOSC÷2÷16=fOSC÷32.
SEC — EPROM Security
When programmed to “1”, this bit disables some functions of the Bootstrap mode, preventing
external reading of EPROM content.
TMR2:TMR0 — Power-on Reset Delay
The amount Power-On Reset delay is set by programming these three bits. The delay is selected
as follows:
Address bit 7
bit 6
bit 5
bit 4
bit 3
bit 2
bit 1
bit 0
