NOTE 1:5V-Tolerent TTL Input pads are as follows:
!
CRT Interface: HSYNC (pin #150), VSYNC (#148)
!
Host Interface: HFS (#98), HCLK (#103), HDATA (#99), RESETN (#100), MFB[11:0]: MFB11 (#123),
MFB10 (#124), MFB9 (#102), MFB8 (#104), MFB7 (#105), MFB6 (#106), MFB5 (#107), MFB4 (#109),
MFB3 (#110), MFB2 (#111), MFB1 (#112), MFB0 (#113)
!
OSD Interface: OSD_DATA3 (#121), OSD_DATA2 (#120), OSD_DATA1 (#119), OSD_DATA0 (#118),
OSD_FSW (#122)
!
Non-5V-Tolerant TTL Input Pad is: TCLK(#141)
NOTE 2: When the panel interface is disabled, the supply current is 0 mA. The drive current of each pad can be
programmed in the range of 2 mA to 20 mA (@capacitive loading = 10 pF)
NOTE 3: When all circuits are powered down and TCLK is stopped, the CVDD supply current becomes 0 mA.
