Programmable Registers
7.5.6 APBX DMA Channel 0 Current Command Address Register
The APBX DMA Channel 0 current command address register points to the multiword
command that is currently being executed. Commands are threaded on the command address.
APBX DMA Channel 0 is controlled by a variable sized command structure. This register
points to the command structure currently being executed.
EXAMPLE
pCurCmd = (hw_apbx_chn_cmd_t *) HW_APBX_CHn_CURCMDAR_RD(0);
register, since there is only one field
pCurCmd = (hw_apbx_chn_cmd_t *) BF_RDn(APBX_CHn_CURCMDAR, 0, CMD_ADDR);
multi-register bitfield read macro
pCurCmd = (hw_apbx_chn_cmd_t *) HW_APBX_CHn_CURCMDAR(0).CMD_ADDR;
