Data Format Options
The W93902 automatically converts message codewords received in numeric or alphanumeric format
into ASCII format. Depending on the setting of Conv1, Conv2, PKGSEL, and the function bits in the
received address codeword, conversion takes place as shown in Table 23.
When a conversion from alphanumeric format to ASCII takes place, the received message
codewords are split into message blocks seven bits in length. After the error flag is added, the
message blocks are transferred as message words. In this option, one message word may exceed
two codewords in length.
When a conversion from numeric format to ASCII takes place, the received message codewords are
split into blocks four bits in length, as shown in Table 24. After the error flag is added, the blocks are
transferred as message words.
When a conversion from numeric format to 4-bit package takes place, the received message
codewords are spilt into blocks four bits in length, as shown in Table 25. After the error status bits
ER0 to ER3 are added, the blocks are transferred as message words.
When no conversion takes place, the received message codewords are spilt into blocks eight bits in
length. The last four bits are combined with the error status bits ER0 to ER3, and then the blocks are
transferred as message words.
