CHAPTER 14 SERIAL INTERFACE (SIO1) In 6-byte transmission (bit 6 (ARLD0) and bit 7 (RE0) of the automatic data transmit/receive control register (ADTC0) are 0) in basic transmit mode, buffer RAM operates as follows. (i) Before transmission (refer to Figure 14-12 (a)) After any data has been written to SIO1 (start trigger: this data is not transferred), transmit data 1 (T1) is transferred from the buffer RAM to SIO1. When transmission of the first byte is completed, ADTP0 is decremented. Then transmit data 2 (T2) is transferred from the buffer RAM to SIO1. (ii) 4th byte transmission point (refer to Figure 14-12 (b)) Transmission of the third byte is completed, and transmit data 4 (T4) is transferred from the buffer RAM to SIO1. When transmission of the fourth byte is completed, ADTP0 is decremented. (iii) Completion of transmission/reception (refer to Figure 14-12 (c)) When transmission of the sixth byte is completed, the interrupt request flag (CSIIF1) is set (INTCSI1 generation). Figure 14-12.
