Notes:
1. ZCS1, CS2, ZWR, ZRD, RS, MI, DW, DB, KIN[7:0], TESTMD and TESTI are inputs. KIN[7:0]
built-in pull up resistors. The TESTMD and TESTI built-in pull down resistors.
2. INT, BUSY, CLK_OUT, PWM_OUT, KOUT[7:0], LP, FR, YD, ZDOFF, XCK and LD[7:0] are
outputs.
3. DATA[7:0] are Bi-direction.
4. The ZRST are Schmitt-trigger with pull-up input. The pulse width on ZRST must be at least
1024*tc. Note that pulses of more than a few seconds will cause DC voltages to be applied to
the LCD panel.
Case1: VDDP = VDD = AVDD = 3.3V, VDDH = NC, LCD Driver VDD = 5V, CLK = 4MHz, CLK_OUT:
Off, Segment=160, Common=160, FRM = 78Hz, TA=25℃.
Case2: VDDP = VDDH = 5V, VDD = AVDD = 3V, LCD Driver VDD = 3.3V, CLK = 4MHz, CLK_OUT:
Off, Segment=160, Common=160, FRM = 78Hz, TA=25℃.
