Description
17.2.3 Master General Purpose Control Register (AXBS_MGPCRn)
The MGPCR controls only whether the master’s undefined length burst accesses are
allowed to complete uninterrupted or whether they can be broken by requests from higher
priority masters. The MGPCR can only be accessed in Supervisor mode with 32-bit
accesses.
Addresses: AXBS_MGPCR0 is 4000_4000h base + 800h offset = 4000_4800h
AXBS_MGPCR1 is 4000_4000h base + 900h offset = 4000_4900h
AXBS_MGPCR2 is 4000_4000h base + A00h offset = 4000_4A00h
AXBS_MGPCR3 is 4000_4000h base + B00h offset = 4000_4B00h
AXBS_MGPCR4 is 4000_4000h base + C00h offset = 4000_4C00h
AXBS_MGPCR5 is 4000_4000h base + D00h offset = 4000_4D00h
AXBS_MGPCR6 is 4000_4000h base + E00h offset = 4000_4E00h
AXBS_MGPCR7 is 4000_4000h base + F00h offset = 4000_4F00h

Arbitrates on undefined length bursts
Determines whether, and when, the crossbar switch arbitrates away the slave port the master owns when
the master is performing undefined length burst accesses.
000 No arbitration is allowed during an undefined length burst
001 Arbitration is allowed at any time during an undefined length burst
010 Arbitration is allowed after four beats of an undefined length burst
011 Arbitration is allowed after eight beats of an undefined length burst
100 Arbitration is allowed after 16 beats of an undefined length burst
