map of the option PROM. The option data can be written by a standard EPROM programmer.
OTPROM option bit map
Notes: Default values are all ‘1’.
T
OSC
: One oscillation clock cycle time
When the bit 0 of “3FF3
H
” is “0”, it activates the option setting for the Low Voltage Reset Control register.
When this option is activated, software setting in the register has no effect.
