Operating Modes and On-Chip Memory
Technical Data
84
IRV(NE) — Internal Read Visibility (Not E) Bit
PSEL[3:0] — Priority Select Bits
Special test
Single chip
Expanded
Bootstrap
IRVNE can be written once in any mode. In expanded modes, IRVNE
determines whether IRV is on or off. In special test mode, IRVNE is
reset to 1. In all other modes, IRVNE is reset to 0. For the
MC68HC811E2, this bit is IRV and only controls the internal read
visibility function.
In single-chip modes this bit determines whether the E clock drives
out from the chip. For the MC68HC811E2, this bit has no meaning or
effect in single-chip and bootstrap modes.
Refer to
Mode
0 = No internal read visibility on external bus
1 = Data from internal reads is driven out the external data bus.
0 = E is driven out from the chip.
1 = E pin is driven low. Refer to the following table.
