7632D–MP3–01/07
Figure 106. SIO Block Diagram
The character consists of five fields: start, data, parity, stop and guard fields.
Figure 107 shows a character example with 8 data bits, 1 parity bit, 2 stop bits and 2
guard bits.
Figure 107. Character Format Example
The start field is fixed and composed of 1 bit transmitted or received at low level.
The data field is composed of 7 or 8 bits by programming DLEN bit in SCON according
to Table 237. The least significant bit is always first transmitted.
Table 237. Data Bit Number Selection
The parity field is optional and enabled by PBEN bit in SCON. This field is composed of
1 bit and its mode is programmable by PMOD1:0 bits in SCON according to Table 238.
Table 238. Parity Mode Selection
The stop field is composed of 1 or 2 bits transmitted or received at high level by pro-
gramming STOP bit in SCON according to Table 239.
