<> 144:ef7eb2e8f9f7 115 (+) de-Initializes common part of the HAL
<> 144:ef7eb2e8f9f7 116 (+) Configure The time base source to have 1ms time base with a dedicated
<> 144:ef7eb2e8f9f7 117 Tick interrupt priority.
<> 144:ef7eb2e8f9f7 118 (++) Systick timer is used by default as source of time base, but user
<> 144:ef7eb2e8f9f7 119 can eventually implement his proper time base source (a general purpose
<> 144:ef7eb2e8f9f7 120 timer for example or other time source), keeping in mind that Time base
<> 144:ef7eb2e8f9f7 121 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and

<> 144:ef7eb2e8f9f7 123 (++) Time base configuration function (HAL_InitTick ()) is called automatically

<> 144:ef7eb2e8f9f7 125 when clock is configured, by HAL_RCC_ClockConfig().
<> 144:ef7eb2e8f9f7 126 (++) Source of time base is configured to generate interrupts at regular

<> 144:ef7eb2e8f9f7 128 peripheral ISR process, the Tick interrupt line must have higher priority
<> 144:ef7eb2e8f9f7 129 (numerically lower) than the peripheral interrupt. Otherwise the caller
<> 144:ef7eb2e8f9f7 130 ISR process will be blocked.
<> 144:ef7eb2e8f9f7 131 (++) functions affecting time base configurations are declared as __weak
<> 144:ef7eb2e8f9f7 132 to make override possible in case of other implementations in user file.
