8 / 14 page MYSON TECHNOLOGY MTV012E MTV012E Revision 1.2 12/23/1998 8/14 = 0 → HSYNC input is negative polarity. Vpol = 1 → VSYNC (CVSYNC) is positive polarity. = 0 → VSYNC (CVSYNC) is negative polarity. Hpre = 1 → HSYNC input is present. = 0 → HSYNC input is not present. Vpre = 1 → VSYNC input is present. = 0 → VSYNC input is not present. Hoff* = 1 → HSYNC input's off-level is high. = 0 → HSYNC input's off-level is low. Voff* = 1 → VSYNC input's off-level is high. = 0 → VSYNC input's off-level is low. *Hoff and Voff are valid when Hpre=0 or Vpre=0. HCNTH (r) : H-Freq counter's high bits. Hovf = 1 → H-Freq counter overflows; this bit is cleared by H/W when condition removed. HF10 - HF8 : 3 high bits of H-Freq counter. HCNTL (r) : H-Freq counter's low bits. VCNTH (r) : V-Freq counter's high bits. Vovf = 1 → V-Freq counter overflows; this bit is cleared by H/W when condition removed. VF8 : High bit of V-Freq counter. VCNTL (r) : V-Freq counter's low bits. PCTR0 (w) : SYNC processor control register 0. C1, C0 = 1,1 → Selects CVSYNC as the polarity, freq and VBLANK source. = 1,0 → Selects VSYNC as the polarity, freq and VBLANK source. = 0,0 → Disables composite function (MTV012 compatible mode). = 0,1 → H/W auto switch to CVSYNC when CVpre=1 and VSpre=0. HVsel = 1 → Pin #16 is P41, pin #17 is P40. = 0 → Pin #16 is HBLANK, pin #17 is VBLANK. STOsel = 1 → Pin #29 is P42. = 0 → Pin #29 is STOUT. PREFS = 0 → Selects 8MHz OSC as H/V present check and self-test pattern time base. = 1 → Selects 12MHz OSC as H/V present check and self-test pattern time base. HALFV = 1 → VBLANK is half frequency output of VSYNC. HBpl = 1 → Negative polarity HBLANK output. = 0 → Positive polarity HBLANK output. VBpl = 1 → Negative polarity VBLANK output. = 0 → Positive polarity VBLANK output. PCTR2 (w) : Self-test pattern generator control. Selft = 1 → Enables generator. = 0 → Disables generator. STbsh = 1 → 63.5KHz (horizontal) output selected. = 0 → 31.75KHz (horizontal) output selected. Rt1,Rt0 = 0,0 → Positive cross-hatch pattern output. = 0,1 → Negative cross-hatch pattern output. = 1,0 → Full white pattern output. = 1,1 → Full black pattern output. |
