Description
2.3.14
RTC (real-time clock) and backup registers
The RTC and the backup registers are supplied through a switch that takes power either on
VDD supply when present or through the VBAT pin. The backup registers are forty-two 16-bit
registers used to store 84 bytes of user application data when VDD power is not present.
They are not reset by a system or power reset, and they are not reset when the device
wakes up from the Standby mode.
The real-time clock provides a set of continuously running counters which can be used with
suitable software to provide a clock calendar function, and provides an alarm interrupt and a
periodic interrupt. It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the
internal low power RC oscillator or the high-speed external clock divided by 128. The
internal low-speed RC has a typical frequency of 40 kHz. The RTC can be calibrated using
an external 512 Hz output to compensate for any natural quartz deviation. The RTC features
a 32-bit programmable counter for long term measurement using the Compare register to
generate an alarm. A 20-bit prescaler is used for the time base clock and is by default
configured to generate a time base of 1 second from a clock at 32.768 kHz.
2.4
Timers and watchdogs
The STM32F105xx and STM32F107xx devices include six general-purpose timers, two
basic timers and two watchdog timers.
Table 4 compares the features of the general-purpose and basic timers.
2.4.1
Advanced-control timer (TIM1)
The advanced control timer (TIM1) can be seen as a three-phase PWM multiplexed on 6
channels. It has complementary PWM outputs with programmable inserted dead-times. It
can also be seen as a complete general-purpose timer. The 4 independent channels can be
used for:
●
Input capture
●
Output compare
●
PWM generation (edge or center-aligned modes)
●
One-pulse mode output
