Character length in bits per character. LEN can be either 32-bits, or 4- to 16-bits that are shown as follows:
0000 32-bit characters
0001–0010 Reserved, causes erratic behavior.
0011 4-bit characters
…
1111 16-bit characters
The TX and RX registers (SPITD, SPIRD) hold 32 bits at a time. A character length of 32 bits fills the TX and
RX registers; therefore, all of the bits in these registers are valid. However, if the character length selected by
LEN is equal or less than 16 bits, then the valid bits will reside in the lower half-word of the transmit and
receive registers. For example, if the character length is set to 16 bits than the valid bits will be 16–31, if the
character length is set to 5 bits that the valid bits will be16–20. Note that the transmit and receive registers
each can hold only one character regardless of the character length.
Prescale modulus select. Specifies the divide ratio of the prescale divider in the SPI clock generator. The SPI
baud rate generator clock source (either input clock or input clock divided by 16, depending on DIV16 bit) is
divided by 4 * ([PM] + 1), a range from 4 to 64. The clock has a 50% duty cycle. For example, if the prescale
modulus is set to PM = 0011 and DIV16 is set, the system/SPICLK clock ratio will be
16 * (4 * (0011 + 1)) = 256.
In slave mode this field must be cleared.
