6. Control and Status Registers
The following tables give definitions for the VPX control
and status registers. The number of bits indicated for
each register in the table is the number of bits imple-
mented in the hardware, i.e. a 9-bit register must always
be accessed using two data bytes, but the 7 MSB will be
“0” on write operations and don’t care on read opera-
tions. Write registers that can be read back are indicated
in the mode column.
The control register modes are
– w
write-only register
– r
read-only register
– w/r
write/read register
– d
register is double latched
– v
register is latched with vsync
Default values are initialized at reset. The mnemonics
used in the Micronas VPX demo software are given in
the last column.
