LCD parallel interface
The FSMC can be configured to interface seamlessly with most graphic LCD controllers. It
supports the Intel 8080 and Motorola 6800 modes, and is flexible enough to adapt to
specific LCD interfaces. This LCD parallel interface capability makes it easy to build cost-
effective graphic applications using LCD modules with embedded controllers or high-
performance solutions using external controllers with dedicated acceleration.
Nested vectored interrupt controller (NVIC)
The STM32F103xC, STM32F103xD and STM32F103xE performance line embeds a nested
vectored interrupt controller able to handle up to 60 maskable interrupt channels (not
including the 16 interrupt lines of Cortex™-M3) and 16 priority levels.

This hardware block provides flexible interrupt management features with minimal interrupt
latency.
External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 19 edge detector lines used to generate
interrupt/event requests. Each line can be independently configured to select the trigger
event (rising edge, falling edge, both) and can be masked independently. A pending register
maintains the status of the interrupt requests. The EXTI can detect an external line with a
pulse width shorter than the Internal APB2 clock period. Up to 112 GPIOs can be connected
to the 16 external interrupt lines.
Clocks and startup
System clock selection is performed on startup, however the internal RC 8 MHz oscillator is
selected as default CPU clock on reset. An external 4-16 MHz clock can be selected, in
which case it is monitored for failure. If failure is detected, the system automatically switches
back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full
interrupt management of the PLL clock entry is available when necessary (for example with
failure of an indirectly used external oscillator).
Several prescalers allow the configuration of the AHB frequency, the high speed APB
(APB2) and the low speed APB (APB1) domains. The maximum frequency of the AHB and
the high speed APB domains is 72 MHz. The maximum allowed frequency of the low speed
APB domain is 36 MHz. See
