6.14.1.4.1 Test Register (0x1A)

Table 6-37 describes the bit fields of the Test register at 0x1A.

Default Value: 0x00, set at POR = H and EN = L

Table 6-37 Test Register (0x1A) (for Test or Direct Use)

BIT NO. BIT NAME FUNCTION DESCRIPTION
B7 OOK_Subc_In Subcarrier input OOK pin becomes decoder digital input
B6 MOD_Subc_Out Subcarrier output MOD pin becomes receiver subcarrier output
B5 MOD_Direct Direct TX modulation and RX reset MOD pin becomes receiver subcarrier output
B4 o_sel First stage output selection

0 = First stage output used for analog out and digitizing

1 = Second stage output used for analog out and digitizing
B3 low2 Second stage gain –6 dB, HP corner frequency / 2
B2 low1 First stage gain –6 dB, HP corner frequency / 2
B1 zun Input followers test
B0 Test_AGC AGC test, AGC level is seen on rssi_210 bits
