CPU mode register
(Address 00FB16)
These bits must always be set to “0”.
Stack page selection bit (Note 1)
0 : In page 0 area
1 : In page 1 area
Nothing is allocated (The value is undefined at reading)
S50, P51/XCIN, XCOUT selection bit (Note 2)
0 : P50, P51
1 : XCIN, XCOUT
XCOUT drive capacity selection bit (Note 2)
0 : Low
1 : High
Clock (XIN-XOUT) stop bit (Note 2)
0 : Oscillates
