ECP/EPP PARALLEL PRINTER PORT WITH 16-BYTE FIFO
REV. 5.1.0
3.9
TEST FIFO ( T-FIFO )
This port is available for programmed I/O and DMA access. Data written to this port is stored in the FIFO if
FIFO-F = 0 and will be lost if FIFO-F = 1. During a read cycle from this port a FIFO under-run will return last
data read and FIFO-E remains coherent.

CONFIGURATION REGISTER A ( Cnfg-A )
This read-only register is available in ECR mode 111 only.
Cnfg-A Bits 1-0:
Forced to logic zero, this field is don’t care for PWord = 1 byte.
Cnfg-A Bit-2:
When transmitting, there is 1 byte waiting to be transmitted that does not affect FIFO-F.
Cnfg-A Bit-3:
Reserved, logic zero.
Cnfg-A Bits 6-4:
Indicates PWord = 1 byte (8-bit implementation).
Cnfg-A Bit-7:
Indicates ECP interrupts are pulsed.
3.11
CONFIGURATION REGISTER B ( Cnfg-B )
This register is available in ECR mode 111 only, and returns bits 0-5 as logic zero for the ST78C36CJ44. The
ST78C36CQ64 will allow programmed selection of the Interrupt and DMA channels after a system RESET
state of 001011 (bits 0-5).
Cnfg-B Bits 2-0:
With bit 2 forced low, select an 8-bit DMA channel per the following table:
