TMP88CS38/CM38A/CP38A
Function
2-bit programmable input/output port.
Each bit of these ports can be Vertical synchronous signal input
individually configured as an input or
an output under software control.
During reset, all bits are configured as Horizontal synchronous signal input
inputs.
Resonator connecting pins. For inputting external clock, XIN is used and XOUT
is opened.
Reset signal input or watchdog timer output/address-trap-reset
output/system-clock-reset output
Test pin for out-going test. Be tied to low.
