196 / 248 page  TMP93CS40/TMP93CS41 2004-02-10 93CS40-194 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 only is used for the purposes of this explanation. • Setting the master controller Main P9CR ← X X − − − − 01 P9FC ← X X − X − XX 1 Select P90 as TXD0 pin and P91 as RXD0 pin. INTES0 ← 1 1 0 0110 1 Enable INTTX0 and set interrupt level 4. Enable INTRX0 and set interrupt level 5. SC0MOD ← 1 0 1 0111 0 Set φ1 as the transmission clock in 9-bit UART mode. SC0BUF ← 0 0 0 0000 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 Main P9CR ← X X − − − − 01 P9FC ← X X − X − XX 1 ODE ← X X X X X X − 1 Select P91 as RXD0 pin and P90 as TXD0 pin (Open-drain output). INTES0 ← 1 1 0 1111 0 Enable INTRX0 and INTTX0. SC0MOD ← 0 0 1 1111 0 Set <WU> to 1 in 9-bit UART transmission mode with transfer clock φ1. INTRX0 interrupt Acc ← SC0BUF if Acc = Select code Then SC0MOD ← − − − 0 − − − − Clear <WU> to 0. Master RXD TXD Slave 1 RXD TXD Slave 2 RXD TXD Select code 00000001 Select code 00001010 |
