Timer break function DMA request bit (BDE) documentation error (RM0091)?

In the description of a break function of TIM1 there is the following statement (in 16.3.12):

The break status flag (BIF bit in the TIMx_SR register) is set. An interrupt can be
generated if the BIE bit in the TIMx_DIER register is set. A DMA request can be sent if
the BDE bit in the TIMx_DIER register is set.

I really need this functionality, but there's no BDE bit neither in register description (16.4.4 - TIM1_DIER) nor in header files (CMSIS/stm32f030x6.h - no TIM_DIER_BDE bit).

Does this bit really exist in the STM32F0x MCU or it is a documentation error?
