16.1.3 Voltage Regulator Option
16.1.4 SVLD and Input Comp Level Option
The chosen value is called V
16.1.5 Debouncer frequency Option
16.1.6 User defined LCD Segment allocation
(For ROM Version) If using a different segment allocation from the one described in chapter 12.3, one needs
to fill in the table below.
The segment allocation connections are realized with the interconnect Metal 2 mask.
The customer should specify the required options at the time of ordering. A copy of
the pages 44 to 46 as well as the « Software ROM characteristic file » generated by
the assembler (*.STA) should be attached to the order. Also the Customer package

(For ROM Version) By default the internal voltage
regulator supplies the core logic the RAM and the
ROM. With option MVreg(A) the regulator is cut and
Vbat is supplying the core logic the ROM and the
RAM.
(For ROM Version) By default the level is 2.4 Volts.
The maximum value is 3.3 Volt and the minimum is
1.2 Volts.
Before choosing a value other than the default,
please contact EM Microelectronic Marin SA, to check
for already existing levels.
(For ROM Version) By default the debouncer
frequency is ck[11]. The user may choose ck[14]
instead of ck[11].
Ck[14 ]corresponds to maximum 0.25ms debouncer
time in case of a 32kHz oscillator.
