Receiver Control Register
The Receiver Control Register configures the following:
Bit [15..11] – Command Code: These bits are the command code that is sent serially to the processor
that identifies the bits to be written to the Receiver Control Register.
Bit [10] – Pin 16 Func: Selects the function of Pin 16. See Table 10 below.
Bit [9..8] – Valid Data Detector Response Time: When Pin 16 is selected as Valid Data Detector output
these bits set the response time in which the TRC101 will detect the incoming synchronous bit pattern
and issue an interrupt to the host processor. See Table 11 below for response settings.
