Action

Arguments and Data

passed via FIFO

Transmits data from FIFO buffer to the

card and activates automatically the

receiver after transmission.

1Ehex

Note: Before the receiver actually

starts, the CL RC632 waits until the

time configured in the register RxWait

has passed.

Data Stream

Note: This command is the

combination of Transmit and Receive
