If register bit AACK_ACK_TIME (register 0x17, XAH_CTRL_1) is set the acknowledgment time
is reduced from 192 µs to 32 µs.
Register 0x0C (TRX_CTRL_2):
The TRX_CTRL_2 register controls the data rate setting
• Bit 7 - RX_SAFE_MODE
Refer to
• Bit [6:2] - Reserved
• Bit [1:0] - OQPSK_DATA_RATE
A write access to these register bits sets the OQPSK PSDU data rate used by the radio trans-
ceiver. The reset value OQPSK_DATA_RATE = 0 is the PSDU data rate according to
IEEE 802.15.4.
