134 / 180 page ![]() TMP93CS32 2004-02-10 93CS32-132 Setting example: To link two slave controllers serially with the master controller, and use the internal clock φ1 as the transfer clock. Since serial channels 0 and 1 operate in exactly the same way, channel 0 is used for the purposes of explanation. • Setting the master controller Main P6CR ← X X − − − − 01 P6FC ← X X − X − 0X 1 Select P60 as TXD0 pin and P61 as RXD0 pin. INTES0 ← 1 1 0 0 1 1 0 1 Enable INTTX0 and set the interrupt level 4. Enable INTRX0 and set the interrupt level 5. SC0MOD ← 1 0 1 0 1 1 1 0 Set φ1 as the transmission clock in 9-bit UART mode. SC0BUF ← 0 0 0 0 0 0 0 1 Set the select code for slave controller 1. INTTX0 interrupt SC0MOD ← 0 − − − − − − − Sets TB8 to“0”. SC0BUF ← * * * * * * * * Set data for transmission. • Setting the slave controller 1 Main P6CR ← X X − − − − 01 P6FC ← X X − X − 0X 1 ODE ← X X X X X X − 1 Select P61 as RXD0 pin and P60 as TXD0 pin (open-drain output). INTES0 ← 1 1 0 1 1 1 1 0 Enable INTRX0 and INTTX0. SC0MOD ← 0 0 1 1 1 1 1 0 Set <WU> to “1” in the 9-bit UART transmission mode with transfer clock φ1. INTRX0 interrupt Acc ← SC0BUF if Acc = Select code Then SC0MOD ← − − − 0 − − − − Clear <WU> to “0”. TXD RXD Master TXD RXD Slave 1 TXD RXD Slave 2 Select code 00000001 Select code 00001010 |
