NOTES
1 All BD (bidirectional) pins except INST and CLKOUT INST and CLKOUT are excluded due to their not being weakly
pulled high in reset BD pins include Port1 Port2 Port3 Port4 Port5 and Port6 except SPLINT (P5 4) and HLDA (P2 6)
2 Standard input pins include XTAL1 EA RESET and Port 1 2 5 6 when setup as inputs
3 All bidirectional I O pins when configured as Outputs (Push Pull)
4 Device is static and should operate below 1 Hz but only tested down to 4 MHz
5 Maximum IOL IOH currents per pin will be characterized and published at a later date
6 Typicals are based on limited number of samples and are not guaranteed The values listed are at room temperature and
VREF e VCC e 5 0V
7 Violating these specifications in reset may cause the device to enter test modes (P5 4 and P2 6)
8 When P0 is used as analog inputs refer to A D specifications for this characteristic
9 For temperatures k100 C typical is 10 mA
8XC196CB ADDITIONAL BUS TIMING MODES
The 8XC196CB device has 2 bus timing modes for
external memory interfacing
MODE 3
MODE 0
Mode 0 is the standard timing mode but 1 (mini-
mum) wait state is always inserted in external bus
cycles
Mode 3 is the standard timing mode Use this mode
for systems that emulate the 8XC196KR bus tim-
ings
