5) When using PIC32MZ EBI without an external address decoder (and note that anything that performs logic on addresses can be considered an address decoder -- (an inverter is the only logic needed to create a 1:2 decoder)), a) What is the largest number of external devices that can be connected using the EBI? b) What factor determines how many address pins you should enable? c) What register controls which address pins are enabled? d) What is this register's power on reset state and are any address bits automatically enabled on power on
