Bit Index Default Access Type Description
[NUM_CHNL-1:0] ‘h0 RO

engine_int_req

Engine Interrupt Request. One bit per read or write engine. This register reflects the interrupt source AND with the enable mask register. The position of the H2C bits always starts at bit 0. The position of the C2H bits is the index above the last H2C index, and therefore depends on the NUM_H2C_CHNL parameter. The previous figure shows the packing of H2C and C2H bits.
