ADV7188
GLOBAL STATUS REGISTERS
Three registers provide summary information about the video
decoder. The STATUS_1, STATUS_2, and STATUS_3 registers
contain status bits that report operational information to the user.
Rev. 0 | Page 21 of 112
STATUS_1[7:0] Address 0x10 [7:0]
This read only register provides information about the internal
status of the ADV7188. See CIL[2:0] Count Into Lock, Address
0x51 [2:0] and COL[2:0] Count Out of Lock, Address 0x51 [5:3]
for information on the timing.
Depending on the setting of the FSCLE bit, the STATUS_1[0]
and STATUS_1[1] bits are based solely on horizontal timing
information or on the horizontal timing and lock status of the
color subcarrier. See the FSCLE Fsc Lock Enable, Address 0x51
[7] section.
STATUS_2[7:0], Address 0x12 [7:0]
See Table 22.
STATUS_3[7:0], Address 0x13 [7:0]
See Table 23.
AD_RESULT[2:0] Autodetection Result Address 0x10 [6:4]
These bits report back on the findings from the autodetection
block. For more information on enabling the autodetection
block, see the General Setup section. For information on
configuring it, see the Autodetection of SD Modes section.
