STC1 (0x060 ~ 0x062)
STC1 Register 1 (0x060)
STC1 Register 2 (0x062)
These read-only registers hold the lower 20 bits of
STC value from the internal STC counter of the
GDC21D301A when the GDC21D301A retrieves
the PCR value from the transport packet whose
PID value is activated for decoding. The internal

GDC21D301A
STC counter is clocked at the frequency of input
on CLOCK_27M pin (nominally 27 MHz). In the
GDC21D301A, STC_Extension is written to
STC1_2[15:7] and can be read by user. STC1 is
also read-only register.

STC2 (0x064 ~ 0x066)
STC2 Register 1 (0x064)
STC2 Register 2 (0x066)
These read-only registers hold the lower 20 bits of
STC value from the internal STC counter of the
GDC21D301A when external BOF1 signal is
detected.
STC3 (0x068 ~ 0x06a)
STC3 Register 1 (0x068)
STC3 Register 2 (0x06a)
These read-only registers hold the lower 20 bits of
STC value from the internal STC counter of the
GDC21D301A when external BOF2 signal is
detected.
STC4 (0x06c ~ 0x06e)
STC4 Register 1 (0x06c)
STC4 Register 2 (0x06e)
These read-only registers hold the lower 20 bits of
STC value from the internal STC counter of the
GDC21D301A when external BOF3 signal is
detected.
STC5 (0x070 ~ 0x072)
STC5 Register 1 (0x070)
STC5 Register 2 (0x072)
These read-only registers hold the lower 20 bits of
STC value from the internal STC counter of the
GDC21D301A when STC fetch instruction is
activated(see Instruction Register).
