IEEE 1284-Compatible Parallel Interface
CD1283
Datasheet
75
This special-purpose register allows the local CPU to issue a hard reset of the device through
software. The RCR performs the same function as the CCR in the CD1283, except that the only
command available is the reset command. To maintain binary compatibility with the CD1284, the
CD1283 places the RCR in the address space of either of the two serial channels in the CD1284.
Thus, before issuing the reset command, the local CPU must select either channel 2 or 3 through
the AER. Once that is accomplished, a write of hex 81 to the RCR initiates the internal reset. The
local CPU must wait for the GFRCR to become valid before beginning operation with the device.
