TIM2POS is used to reposition the timer channels for TIM2 to a different pair of pins. This allows the
user to free up one of the communication ports based on application needs.
ESCIBDSRC controls the clock source used for the ESCI. The setting of the bit affects the frequency
at which the ESCI operates.
OSCENINSTOP, when set, will allow the clock source to continue to generate clocks in stop mode.
This function can be used to keep the periodic wakeup running while the rest of the microcontroller
stops. When clear, the clock source is disabled when the microcontroller enters stop mode.
1 = Internal pullup is disconnected
0 = Internal pullup is connected between IRQ pin and V
1 = Interrupt request function active in pin
0 = Interrupt request function inactive in pin
1 = TIM2 timer channel pins share PTB4 and PTB5
0 = TIM2 timer channel pins share PTB1 and PTB2
1 = Internal data bus clock used as clock source for ESCI
0 = BUSCLKX4 used as clock source for ESCI
1 = Oscillator enabled to operate during stop mode
0 = Oscillator disabled during stop mode
1 = Reset function active in pin
0 = Reset function inactive in pin
1 = COP reset short cycle = 8176 × BUSCLKX4
0 = COP reset long cycle = 262,128 × BUSCLKX4

Write:
The RSTEN bit is cleared by a power-on reset (POR) only. Other resets will
leave this bit unaffected.
