TEST FUNCTION
TEST[1:0]
ADJRESULT : out MPX VCO adjustment result
TFCOUT : Fc Frequency divided by N[16:0]
TIF : IF frequency comes in through external source for test
TFCIN : Fc frequency comes in through external source for test
TLEDRSTB : counter reset signal of tuning LED control block comes in through external source for test
TFRIN : Fr frequency comes in through external source for test
TFROUT : Fr frequency divided by R[4:0]
TMPXVCO : MPX VCO free-running frequency which is end of adjusting
TIFMINMAX : Minimum and maximum of IF frequency which is used to check tuning LED operation
0

1 : on adjusting
0 : success in adjustment
1.172kHz : 1st. adjustment cycle is failed, but adjusting 2nd, 3rd adjustment cycle.
TEST[1:0]=0 :inform the state of MPX VCO free-running adjustment
TEST[1:0]=1 : Fc frequency for testing N divider block, Fr frequency for testing X'tal divider block, MPX
VCO free-running frequency for testing MPX VCO self adjusting block
TEST[1:0]=2 : IF frequency, reset signal of LED control counter and IF Min. Max value for testing LED
control block
TEST[1:0]=3 : Fc and Fr frequency for testing PFD and LOCK detector
(1) : If A[1:0] is zero, send the IN1 MODE data latched in DSR to Micro- processor through DO pin
synchronized with falling edge of CL
(2) : If A[1:0] is zero, send the IN2 MODE data latched in DSR to Micro- processor through DO pin
synchronized with falling edge of CL
