PAY[15:8]
Bits 0-7 PAY(15:8): The number of lines of the active
window area {Y-axis dimension]. Upper 8 bits.
Initial Value = 0x00.
The logical value of PAY is the same as its literal
value for all literal values up to and including
0xFFFE. Thus, the logical value for literal PAY =
0xFFFE (65534) is 65534 pixels. The logical value
for literal PAY = 0xFFFF (65535) is 65536 pixels. If
PAY = 0 in compression, then the number of lines
processed is determined by the active period of
VIN. PAY (logical) must be an even number when
vertical decimation/interpolation is used.

PAY[15:8]
Bits 0-7 NOL(15:8): The number of processed lines when
compressing. Upper 8 bits.
Initial Value = PAY(15:8).
If PAY≠0, its logical value determines the number of
lines actually processed in compression. If PAY = 0,
the ZR36016 processes all lines input until the
falling edge of VIN. If the number of lines input
during the active period of VIN is not an exact
multiple of the strip height (see Table 19), then the
ZR36016 will abandon the incomplete strip. The
NOL register will indicate only the number of lines
actually processed.
In the sequential mode, the value read from this
register is the number of lines processed in the
previous VIN active interval.
If 65536 lines are processed, the value in NOL will
be 0x0000. The ZR36016 can process a maximum
of 65536 lines. If the number of lines exceeds
65536, then the ZR36016 terminates the process-
ing after 65536 lines.
