KS8805B UNIVERSAL PROGRAMMABLE PLL
MICOM (MCU) PROGRAM SUMMARY
Program format in MICOM (MCU) - MSB : 1’st input
CLK (Pin 1), AUXDI (Pin 2), DI (Pin 3) and EN (Pin 4) terminals are used for programming.
DATA and CLK terminals are used for loading the data to internal shift-register.
There are two formats which can be controlled by EN (Pin 4) input state.
If the processing state of EN terminal is ‘High’, the control register and reference count register are selected.
If the processing state of EN terminal is ‘Low’, TX-channel count register and RX-channel count register are selected.
Control register programming (8 bits)
In addition to special COC (Bit 6) function which can support the f
MCU
ON / OFF, various operation are included.
