Port Name
Input/Output
Description
sleep
Input
Sleep control.
rst_n
Input
Active low reset signal.
clk
Input
Clock signal.
sleep_status
Output

asserted when the system exits the sleep mode
condition completely.
gpio_pad_output[3:0]
Output
General-purpose I/O (GPIO) output ports.
cnt_value[7:0]
Output
