RTC Mode
Figure 314 shows the timing diagram of the RTC mode. Clock rate for the RTC mode is 4 times slower than
the GLCO clock rate. For PLL frequency control, the upper 22 bits are used. Each frequency control bit is 2
clock cycles long. The active low reset bit occurs 6 CLKs after the transmission of the last bit of PLL frequency
control.

3.21 Internal Control Registers
The TVP5150 device is initialized and controlled by a set of internal registers which set all device operating
parameters. Communication between the external controller and the TVP5150 device is through I2C.
Table 38 shows the summary of these registers. The reserved registers must not be written. However,
reserved bits in the defined registers must be written with 0s. The detailed programming information of each
register is described in the following sections.
