• Bits 5:4 – PMODE[1:0]: Parity Mode
These bits enable and set the type of parity generation according to
When enabled, the transmitter will automatically generate and send the parity of the transmitted
data bits within each frame. The receiver will generate a parity value for the incoming data and
compare it to the PMODE setting, and if a mismatch is detected, the PERR flag in STATUS will
be set.
These bits are unused in master SPI mode operation.
Table 23-7.
• Bit 3 – SBMODE: Stop Bit Mode
This bit selects the number of stop bits to be inserted by the transmitter according to
on page
This bit is unused in master SPI mode operation.
Table 23-8.
• Bit 2:0 – CHSIZE[2:0]: Character Size
The CHSIZE[2:0] bits set the number of data bits in a frame according to
309. The receiver and transmitter use the same setting.
Table 23-9.
PMODE[1:0]
CHSIZE[2:0]
