0xNNN is a 12-bit number for which the ten least significant bits (bits [9:0]) are an IORAM
0,1
address and the two most significant bits
(bits [11:10]) must be 0.
0xNNN is a 12-bit unsigned number for which the most significant bit (bit 11) must be 0.
§ Or reactivate peripheral service in MIOU
0,1
if it has been deactivated by a prior RESET
0,1
command.
Subsequent execution of an ILEN_UP
0,1
command reactivates MIOU
0,1
peripheral service.
