Nothing is assigned.
In an attempt to write to these bits, write "0". The value, if read, turns out to be "0".
Note 1: When using multiple pins to output the transfer clock, the following requirements must be met:
UART1 internal/external clock select bit (bit 3 at address 00A016) = “0”.
Note 2: For P37, select "0" for data receive, and "1" for data transfer. And set the direction register
of port P37 to input ("0") when receiving.
