AFR BIT-6:
INT output polarity.
0= Normal. INT output follows the -ACK input
1= Inverted INT output
AFR BIT-7:
FIFO enable / disable function.
0= FIFO is disabled( default mode).
1= FIFO is enabled. Internal 83 byte of FIFO is
enabled.
FIFO BYTE COUNT REGISTER (FBCR)
State and content of the printer FIFO can be moni-
tored by reading this register.
FCBR BIT 0-6:
FIFO byte count. Number of characters left in FIFO.
FCRB bit-0 is the LSB bit of the counter and FCRB bit-
6 is the MSB bit of the counter.
FBCR BIT-7:
FIFO state.
0= FIFO is enabled
1= FIFO is disabled
