Preliminary specification

Bluetooth Adapter IC

PCF26100

6.5.4

The UAA3558 needs some timing signals which do not have a corresponding signal at the BlueRF interface. These

signals are generated internally in the adapter. The timing values for these will not change dynamically. These values

are programmed into the adapter via the serial interface. The timing words are: S_EN_start, S_EN_width, T_SW_start,

SLCCTR_start, S_EN_PULSE_start, RSSI_start, and GFSK_DC_bias.

Table 14 Timing control word S_EN_start

Table 15 Timing control word S_EN_width

Table 16 Timing control word T_SW_start

Table 17 Timing control word SLCCTR_start

Table 18 Timing control word S_EN_PULSE_start

Table 19 Timing control word RSSI_start

Table 20 Timing control word GFSK_DC_bias
