8266B-MCU Wireless-03/11
• Bit 3:0 – TST_CTRL_DIG3:0 - Digital Test Controller Register
This sub-register selects a test controller function. All values not listed int the following
table are reserved for internal use.
Table 9-73 TST_CTRL_DIG Register Bits
This register contains the frame length information of a received frame. This information
is not stored in the frame buffer. The frame length information is written to this register
after the last received octet.
• Bit 7:0 – RX_LENGTH7:0 - Received Frame Length
These bits contain the length of the last received frame.
First byte of the 128 byte long frame buffer of the TRX24.
• Bit 7:0 – TRXFBST7:0 - Frame Buffer Start Byte
This register is the last byte of the 128 byte long frame buffer of the radio transceiver.
• Bit 7:0 – TRXFBEND7:0 - Frame Buffer End Byte
