Address:
Single chip:
1. The values of the RBOOT, SMOD, and MDA reset bits depend on the mode selected at the
masking by the I bit in the CCR, or by any associated local bits. Interrupt
vectors are not affected by priority assignment. To avoid race conditions,
HPRIO can be written only while I-bit interrupts are inhibited.
RBOOT — Read Bootstrap ROM Bit
SMOD — Special Mode Select Bit
Expanded:
Bootstrap:
RESET pin rising edge. Refer to
Has meaning only when the SMOD bit is a 1 (bootstrap mode or
special test mode). At all other times this bit is clear and cannot be
written. Refer to
for more information.
This bit reflects the inverse of the MODB input pin at the rising edge
of reset. Refer to
