Table 81.
1. Partially tested, guaranteed by design characterization
Figure 57. External bus arbitration (releasing the bus)
1. The ST10F273Z4 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
