data rate can be multiplexed on this signal. Needs external pull-up.
S/T bus receiver input (negative).
S/T bus receiver input (positive).
S/T bus transmitter output (positive).
S/T bus transmitter output (negative).
Crystal or Oscillator clock input. The clock frequency:
7.68MHz 100PPM.
Crystal clock output. Left unconnected when using oscillator.
Used to enable normal operation (1) or enter test mode (0).
Timer 2 output. A square wave with 50 % duty cycle, 1~63 ms period
can be generated.
A level change (either direction) will generate a maskable interrupt on
the interrupt request pin INT#.
A level change (either direction) will generate a maskable interrupt on
the interrupt request pin INT#.
When confiured as simple IO mode (PCTL:XMODE = 0), these pins can
read/write data from/to peripheral components. The pin directions are
selected via register. After hardware reset, the output drivers are
disabled.
When configured as microprocessor mode (PCTL:XMODE = 1),
address and data are multiplexed on these pins.
When configured as microprocessor mode (PCTL:XMODE = 1), this is
the Address Latch Enable output.
When configured as microprocessor mode (PCTL:XMODE = 1), this is
the read pulse.
When configured as microprocessor mode (PCTL:XMODE = 1), this is
the write pulse.
Digital Power Supply (5V 5%).
