2 PIN DESCRIPTION
Figure 2. 20-Pin SO Package Pinout
Notes:
1. This pin cannot be configured as external interrupt in ROM devices.
2. OSC1 and OSC2 are not multiplexed in ROM devices and Port C is not present.
Legend / Abbreviations for Table 1:
Type:
I = input, O = output, S = supply
In/Output level: CT = CMOS 0.3VDD /0.7VDD with input trigger
Output level:
HS = 20mA high sink (on N-buffer only)
Port and control configuration:
– Input:
float = floating, wpu = weak pull-up, int = interrupt, ana = analog
– Output:
OD = open drain, PP = push-pull
The RESET configuration of each pin (shown in bold) is valid as long as the device is in reset state.
