10.3.1
RBOOT, SMOD, and MDA bits depend on power-up initialization mode and can only be written in
special modes when SMOD = 1. Refer to Table 3-4.
RBOOT — Read bootstrap ROM (refer to Section 3)
SMOD — Special mode select (refer to Section 3)
MDA — Mode select A (refer to Section 3)
PSEL[4:0] — Priority select bits
These bits select one interrupt source to be elevated above all other I-bit-related sources and can
be written to only while the I-bit in the CCR is set (interrupts disabled). See Table 10-4.
