OPTION BYTES (Cont’d)
OPTION BYTE 1
OPT7 = PLLx4x8 PLL Factor selection.
0: PLLx4
1: PLLx8
OPT6 = PLLOFF PLL disable.
0: PLL enabled
1: PLL disabled (by-passed)
OPT5 = PLL32OFF 32MHz PLL disable.
0: PLL32 enabled
1: PLL32 disabled (by-passed)
OPT4 = OSC RC Oscillator selection
0: RC oscillator on
1: RC oscillator off
Notes:
– 1% RC oscillator available on ST7LITE15B and
ST7LITE19B devices only
– If the RC oscillator is selected, then to improve
clock stability and frequency accuracy, it is rec-
ommended to place a decoupling capacitor, typ-
ically 100nF, between the VDD and VSS pins as
close as possible to the ST7 device.
OPT3:2 = LVD[1:0] Low voltage detection selec-
tion
These option bits enable the LVD block with a se-
lected threshold as shown in Table 26.
Table 26. LVD Threshold Configuration
OPT1 = WDG SW Hardware or Software
Watchdog
This option bit selects the watchdog type.
0: Hardware (watchdog always enabled)
1: Software (watchdog to be enabled by software)
OPT0 = WDG HALT Watchdog Reset on Halt
This option bit determines if a RESET is generated
when entering HALT mode while the Watchdog is
active.
0: No Reset generation when entering Halt mode
1: Reset generation when entering Halt mode
