Transfer of customer code
Customer code is made up of the ROM/FASTROM contents and the list of the selected
options (if any). The ROM/FASTROM contents are to be sent with the S19 hexadecimal file
generated by the development tool. All unused bytes must be set to FFh. Complete the
appended
the selected options to STMicroelectronics.
Refer to application note AN1635 for information on the counter listing returned by ST after
code has been transferred.

PLL OFF
Name
PLL activation
This option bit activates the PLL which allows multiplication by two of
the main input clock frequency. The PLL must not be used with the
internal RC oscillator. The PLL is guaranteed only with an input
frequency between 2 and 4 MHz.
0: PLL x2 enabled
1: PLL x2 disabled
Caution: The PLL can be enabled only if the “OSCRANGE” (OPT3:1)
bits are configured to “MP - 2~4 MHz”. Otherwise, the device
functionality is not guaranteed.
