The SPI Master generates an rx/tx interrupt as soon as the system reset is disabled. The following line generates an interrupt because s_int_tx and s_int_rx are both high:
assign events_o[0] = s_int_tx | s_int_rx;
which has to do with the fact that the r_state_tx and r_state_rx state are set to INT_Tx_ACTIVE in reset mode, which causes the SPI controller to issue an interrupt as soon as the interrupts are enabled:
apb_spi_master.sv: line 120
always_ff @(posedge HCLK, negedge HRESETn)
begin
if(~HRESETn)
begin
r_state_tx <= INT_TX_ACTIVE;
r_state_rx <= INT_RX_ACTIVE;
end
else
...
Is there a reason why the reset state is INT_Tx_ACTIVE instead of INT_Tx_INACTIVE?
