Description
SC132 v1.0 (www.scc.me.uk)
Z80 Serial Input/Output (SIO/0) module for RC2014
Features:
- Full Z80 mode 2 interrupt support (IEI/IEO daisy-chain)
- Compatibility option for both register orders used by RC2014
- Two TTL serial ports for use with FTDI serial adpter cables
- Source of bus clock (option) to potentially reduce board count
- On-board clock option to make it independent of the CPU clock
- Baud rate controllable in software when used with SC102 Z80 CTC
