Write to a Clock Prescale Register

The clock prescale registers are written by sending a four-byte sequence beginning with W or w.

Wnmm	Write an 8-bit value to a Clock Prescale register.
	n	Number of the Clock Prescale register to be written. 0 is input channel 0;
		1 is input channel 1.
	mm	Hexadecimal value to write to the register.

The UART responds with the four-character sequence return linefeed > space.

Write to an Input Configuration Register

The input configuration registers are written by sending a six-byte sequence beginning with W or w.

Wnmmmm Write a 16-bit value to an Input Configuration register.

nNumber of the Input Configuration register to be written. 2 is input channel 0; 3 is input channel 1.

mmmmHexadecimal value to write to the register.

The UART responds with the four-character sequence return linefeed > space.

Read from a Clock Prescale Register

The Clock Prescale registers are read by sending a two-byte sequence beginning with R or r.

Rn	Read an 8-bit value from a Clock Prescale register.
	n	Number of the Clock Prescale register to be read. 0 is input channel 0; 1
		is input channel 1.

The UART responds with the six-character sequence xx return linefeed > space, where xx is the two- character hexadecimal value read from the 8-bit register.

Read from an Input Configuration Register

The Input Configuration registers are read by sending a two-byte sequence beginning with R or r.

Rn	Read a 16-bit value from a Input Configuration register.
	n	Number of the Input Configuration register to be written. 2 is input
		channel 0; 3 is input channel 1.

The UART responds with the eight-character sequence xxxx return linefeed > space, where xxxx is the four-character hexadecimal value read from the 16-bit register.
