1. The DAC integrates an output buffer that can be used to reduce the output impedance and to drive external loads directly
without the use of an external operational amplifier. The buffer can be bypassed by configuring the BOFFx bit in the
DAC_CR register.
5.3.25 FSMC characteristics
Asynchronous waveforms and timings
Figure 52 through Figure 55 represent asynchronous waveforms and Table 71 through
Table 74 provide the corresponding timings. The results shown in these tables are obtained
with the following FSMC configuration:
● AddressSetupTime = 1
● AddressHoldTime = 0x1
● DataSetupTime = 0x1
● BusTurnAroundDuration = 0x0
In all timing tables, the T_HCLK is the HCLK clock period.
