User manual
3.3.1.1 Examples of AHB1 settings
3.3.2 AHB Arbiter Configuration register 2 (AHBCFG2 - 0xE01F C18C)
The following examples use the LPC2478 to illustrate how to select the priority of each
AHB1 master based on different system requirements.
Table 31.
Table 32.
Table 33.
[1]
Table 34.
[1]
By default, the AHB2 access is scheduled round-robin (bit 0 = 1). For round-robin
scheduling, the default priority sequence will be Ethernet and CPU.
The AHB2 access priority can be configured as priority scheduling (bit 0 = 0) and priority
of the each of the AHB2 bus masters can be set by writing the priority value (highest
priority = 2, lowest priority = 1).
