Description
42 [15:10] SLOTA_AFE_MODE 0x07 Not applicable In normal mode, this setting configures the integrator block
for optimal operation. This setting is not important for TIA
ADC mode.
[9:8] SLOTA_INT_GAIN 0x0 0x0 00: buffer gain = 1.0.
01: buffer gain = 1.0.
10: buffer gain = 0.7.
7 SLOTA_INT_AS_BUF 0x0 0x1 0: normal integrator configuration.
1: convert integrator to buffer amplifier
43 [15:0] SLOTA_AFE_CFG 0xADA5 0xAE65 Time Slot A AFE connection.
0xAE65 bypasses the band-pass filter.
0xB065 can also be used in TIA ADC mode. This setting
bypasses the BPF and the integrator.
44 [15:10] SLOTB_AFE_MODE 0x07 Not applicable In normal mode, this setting configures the integrator block
for optimal operation. This setting is not important for TIA
ADC mode.
[9:8] SLOTB_INT_GAIN 0x0 0x0 00: buffer gain = 1.0.
01: buffer gain = 1.0.
10: buffer gain = 0.7.
7 SLOTB_INT_AS_BUF 0x0 0x1 0: normal integrator configuration.
1: convert integrator to buffer amplifier
45 [15:0] SLOTB_AFE_CFG 0xADA5 0xAE65 Time Slot B AFE connection.
0xAE65 bypasses the BPF.
0xB065 can also be used in TIA ADC mode. This setting
bypasses the BPF and the integrator.
58 7 ENA_INT_AS_BUF 0x0 0x1 Enables the ability to configure the integrator as a buffer in
TIA ADC mode.
