digital VPO-bus output signal; higher bits of the 8-bit output bus. The output data
types of the VPO-bus are controlled via I2C-bus registers LCR2 to LCR24;
see Table 4. If I2C-bus bit VIPB = 1, the higher bits of the digitized input signal are
connected to these outputs, configured by the I2C-bus control signals

digital VPO-bus output signal; lower bits of the 8-bit output bus. The output data types
of the VPO-bus are controlled via I2C-bus registers LCR2 to LCR24; see Table 4.

RTCO
(I/)O real-time control output: contains information about actual system clock frequency,
field rate, odd/even sequence, decoder status, subcarrier frequency and phase and
PAL sequence (see external document “RTC Functional Description”, available on
request); the RTCO pin is enabled via I2C-bus bit OERT; this pin is also used as an
input pin for test purposes and has an internal pull-down resistor; do not
connect any pull-up resistor to this pin

(I/)O real-time signal output 0: multi functional output, controlled by I2C-bus bits
RTSE03 to RTSE00; see Table 49. RTS0 is strapped during power-on or CE driven
reset, defines which I2C-bus slave address is used; 0 = 48H for write, 49H for read,
external pull-down resistor of 3.3 kΩ is needed; 1 = 4AH for write, 4BH for read,
default slave address (default, internal pull-up)
I/O
real-time signal I/O terminal 1: multi functional output, controlled by I2C-bus bit
