MDA — Mode Select A Bit
IRVNE — Internal Read Visibility/Not E Bit
PSEL[3:0] — Priority Select Bits
The mode select A bit reflects the status of the MODA input pin at the
rising edge of reset. Refer to
On-Chip Memory
The IRVNE control bit allows internal read accesses to be available
on the external data bus during operation in expanded modes. In
single-chip and bootstrap modes, IRVNE determines whether the E
clock is driven out an external pin. For the MC68HC811E2, this bit is
IRV and only controls internal read visibility. Refer to
Operating Modes and On-Chip Memory
These bits select one interrupt source to be elevated above all other
I-bit-related sources and can be written only while the I bit in the CCR
is set (interrupts disabled).
