SAF7113H

8.10

Digital output port VPO7 to VPO0

The 8-bit VPO-bus can carry 16 data types in three different formats, selectable by the control registers LCR2 to LCR24

(see also Chapter 15, subaddresses 41H to 57H).

Table 4

VPO-bus data formats and types

Note

1. The number of valid bytes per line can be less for the sliced data format if standard not recognized (wrong standard

or poor input signal).

For each LCR value from 2 to 23 the data type can be

programmed individually. LCR2 to LCR23 refer to line

numbers. The selection in LCR24 values is valid for the

rest of the corresponding field. The upper nibble contains

the value for field 1 (odd), the lower nibble for field 2

(even). The relationship between LCR values and line

numbers can be adjusted via VOFF8 to VOFF0 (located in

subaddresses 5BH, bit 4 and 5AH, bits 7 to 0).

The recommended values are 07H for 50 Hz sources and

0AH for 60 Hz sources, to accommodate line number

conventions as used for PAL, SECAM and

NTSC standards; see Tables 8 to 11.
