CHAPTER 17 SERIAL INTERFACE CHANNEL 1
436
In 6-byte transmission (ARLD = 1, RE = 0) in the repeat transmit mode, buffer RAM operates as follows.
(i)
Before transmission (Refer to Figure 17-15 (a))
After any data has been written to serial I/O shift register 1 (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, automatic data transmit/receive address pointer (ADTP) is decremented. Then
transmit data 2 (T2) is transferred from the buffer RAM to SIO1.
(ii) Upon completion of transmission of 6 bytes (Refer to Figure 17-15 (b))
When transmission of the sixth byte is completed, the interrupt request flag (CSIIF1) is not set.
The ADTP is set with the initial pointer value again.
(iii) 7th byte transmission point (Refer to Figure 17-15 (c))
Transmit data 1 (T1) is transferred from the buffer RAM to SIO1 again. When transmission of the first
byte is completed, ADTP is decremented. Then transmit data 2 (T2) is transferred from the buffer RAM
to SIO1.
