*1) The “L” active and “H” active states of these pins can be selected using the control program for the user system.
”_N” indicates that the “L” active state is the default state.
*2) DSTB0_N and DACK1_N are assigned to the same pin, so the functions of one or the other are valid.
*3) The input level of the MPBUS pin needs to be established just before the end of H/W reset. Also, this should not
be switched during operation.
*4) When CS_N and RD_N are “L”, These pins output “H” or “L”.
*5) If MPBUS is “H”, these pins can be made to open.
*6) CS_N, WR0_N, and WR1_N should be kept as (a) or (b) during RST_N=”L” (from RST_N goes "L" to right after
RST_N goes "H").
(a) CS_N=”H”
(b) WR0_N=”H” and WR1_N=”H”
*7) Description of “State of pin”
(a) Input : Pins are Hi-z state. Please do not make it “open” on a board.
(b) Input(Hi-z) : Pins are Hi-z state. Pins can be “open” on a board.
(c) H, L, H/L : Output states is shown.
*8) These pins are in an inactive state.
