Programmable Registers
HW_APBH_CTRL1_SET: 0x014
HW_APBH_CTRL1_CLR: 0x018
HW_APBH_CTRL1_TOG: 0x01C
This register contains the per channel interrupt status bits and the per channel interrupt
enable bits. Each channel has a dedicated interrupt vector in the vectored interrupt controller.
EXAMPLE
BF_WR(APBH_CTRL1, CH5_CMDCMPLT_IRQ, 0);
BF_APBH_CTRL1.CH5_CMDCMPLT_IRQ = 0;
