User manual
3.3.1 AHB Arbiter Configuration register 1 (AHBCFG1 - 0xE01F C188)
3.3 AHB Configuration
Table 28.
The AHB configuration register allows changing AHB scheduling and arbitration
strategies.
Table 29.
By default, the AHB1 access is scheduled round-robin (bit 0 = 1). For round-robin
scheduling, the default priority sequence will be CPU, DMA, AHB1, USB and LCD.
The AHB1 access priority can be configured as priority scheduling (bit 0 = 0) and priority
of the each of the AHB1 bus masters can be set by writing the priority value (highest
priority = 5, lowest priority = 1).
Masters with the same priority value are scheduled on a round-robin basis.

Description
Assertion of the POR signal sets this bit, and clears all of the other bits in
this register. But if another Reset signal (e.g., External Reset) remains
asserted after the POR signal is negated, then its bit is set. This bit is not
affected by any of the other sources of Reset.
Assertion of the RESET signal sets this bit. This bit is cleared by POR,
but is not affected by WDT or BOD reset.
This bit is set when the Watchdog Timer times out and the WDTRESET
bit in the Watchdog Mode Register is 1. It is cleared by any of the other
sources of Reset.
This bit is set when the 3.3 V power reaches a level below 2.6 V.
If the V
BODR bit will be set to 1.
If the V
decline to the level at which POR is asserted (nominally 1 V), the BODR
bit is cleared.
if the V
above 2.6 V, the BODR will be set to 1.
This bit is not affected by External Reset nor Watchdog Reset.
Note: Only in case when a reset occurs and the POR = 0, the BODR bit
indicates if the V
Reserved, user software should not write ones to reserved bits. The
value read from a reserved bit is not defined.
