Read Plane Select Register
These two bits select the memory plane from which the CPU reads data in Read Mode 0.
In Odd/Even Mode, bit 0 of this register is ignored. In Chain 4 Mode, both bits 1 and 0 of
this register are ignored. The four memory planes are selected as follows:
These two bits also select which of the four memory read latches may be read via the
Memory Read Latch Data Register (CR22). The choice of memory read latch corresponds
to the choice of plane specified in the table above. The Memory Read Latch Data register
and this additional function served by 2 bits are features of the VGA standard that were
never documented by IBM.
