PH8.DS03/Modes+mem
Refer to Table 3-4, which is a summary of mode pin operation, the mode control bits and the four
operating modes.
A normal mode is selected when MODB is logic one during reset. One of three reset vectors is
fetched from address $FFFA–$FFFF, and program execution begins from the address indicated
by this vector. If MODB is logic zero during reset, the special mode reset vector is fetched from
addresses $BFFA–$BFFF and software has access to special test features. Refer to Section 10.
3.3.1.1
Note:
RBOOT — Read bootstrap ROM
SMOD — Special mode select
Once cleared, cannot be set again.
MDA — Mode select A
PSEL[4:0] — Priority select bits (refer to Section 10)

RBOOT, SMOD and MDA bits depend on the power-up initialization mode and can only
be written in special modes when SMOD = 1. Refer to Table 3-4.
