595 / 1032 page  SERIAL INTERFACE 12 12-47 32185/32186 Group Hardware Manual Rev.1.10 REJ09B0235-0110 May 15, 07 Table 12.6.1 Transfer Data in UART Mode Bit Name Content ST (start bit) Indicates the beginning of data transmission. This is "L" level signal of a one bit period, which is added immediately preceding the transmit data. Bits 0–8 (character bits) Transmit/receive data transferred via serial interface. In UART mode, 7, 8 or 9 bits of data can be transmitted/received. PAR (parity bit) Added to the transmit/receive character. When parity is enabled, parity is automatically set in such a way that the number of 1’s in the character including the parity bit itself is always even or odd as selected by the even/odd parity select bit. SP (stop bit) Indicates the end of data transmission, which is added immediately following the character (or if parity is enabled, immediately following the parity bit). The stop bit can be chosen to be one bit or two bits long.
