DRPACK: Data Request Pending Acknowledgement bit⁽¹⁾
Sets or clears the frame pending bit in the Acknowledgement frame for a received data request MAC
command.
1 = Frame pending bit = 1
0 = Frame pending bit = 0
MAWD<6:0>: macAckWaitDuration bit⁽²⁾
The maximum number of symbols to wait for an Acknowledgment frame to arrive following a transmitted
data or MAC command frame. Units: Symbol period (16 μs). Default value: 0x39.
Note 1: Refer to IEEE 802.15.4™-2003 Standard, Section 5.4.2.2 “Data Transfer from a Coordinator” and
Section 7.3 “MAC Command Frames”.
2: Refer to IEEE 802.15.4™-2003 Standard, Table 71: MAC PIB Attributes.
