__IOM uint32_t hifmem_priority_ctrl_Type::extmem_prio_accesstime_ctrl

(@ 0x00000004) Control Register for master channel accesses per timeslot on external meory interface. For detailed priority controlling read note

at extmem_prio_timslot_ctrl-register description.

For netX90 only SDRAM accesses are regarded for timeslot priority, SRAM/FLASH accesses are not. Note: This register can be protected by the register MODULE_FIREWALL_CTRL.firewall_cfg_hifmemct l.

__IOM uint32_t hifmem_priority_ctrl_Type::extmem_prio_timslot_ctrl

(@ 0x00000000) Memory interface master timeslot priority control register. Note: Any master can access in one timeslot ((ts_accessrate_mX*ts_length_mX)/64)

1 times (i.e. at maximum (ts_accessrate_mX)/64 bandwidth on external memory bus, ts_accessrate_mX is programmed by extmem_prio_accesstime_ctrl-register). Priority control will watch data accesses on external memory data bus (SDRAM and non SDRAM), including pauses on non SDRAM-accesses, not including control commands to SDRAM. Any master request
