bits are decoded to form the register address. This bit is placed in this register to simplify
programming when the current state of the Shift right/Shift Left bit is not known.
A hardware reset forces SHIFT LEFT mode where the address is decoded from
AD5–AD0. In SHIFT RIGHT mode, the address is decoded from AD4–AD0. The Shift
Right/Shift Left bit is written using a command to make the software writing to WR0 inde-
pendent of the state of the Shift Right/Shift Left bit.
While in the SHIFT LEFT mode, the register address is placed on AD4–AD0 and the
Channel Select bit A/B, is decoded from AD5. In SHIFT RIGHT mode, the register
address is again placed on AD4–AD1 but the Channel Select A/B is decoded from AD0.
Since Z80230 does not contain 16 read registers, the decoding of the read registers is not
complete; this state is indicated in Tables 4 and 5 by parentheses around the register name.
These addresses may also be used to access the read registers. The Z80230 contains only
one WR2 and WR9; these registers may be written from either channel.
SHIFT LEFT mode is used when Channel A and B are programmed differently. Using
SHIFT LEFT mode allows the software to sequence through the registers of one channel
at a time. The SHIFT RIGHT mode is used when the channels are programmed the same.
By incrementing the address, the user can program the same data value into both Channel
A and Channel B registers.
