Table 82.
1. Partially tested, guaranteed by design characterization.
Figure 62. External bus arbitration (releasing the bus)
1. The ST10F272Z2 will complete the currently running bus cycle before granting bus access.
2. This is the first possibility for BREQ to become active.
3. The CS outputs will be resistive high (pull-up) after t
