Chapter 6 Parallel Input/Output
PTASEn — Slew Rate Control Enable for Port A Bit n (n = 0–7)
PTADDn — Data Direction for Port A Bit n (n = 0–7)
6.6.2
Port B includes eight general-purpose I/O pins that share with the ATD function. Port B pins used as
general-purpose I/O pins are controlled by the port B data (PTBD), data direction (PTBDD), pullup enable
(PTBPE), and slew rate control (PTBSE) registers.
If the ATD takes control of a port B pin, the corresponding PTBDD, PTBSE, and PTBPE bits are ignored.
When a port B pin is being used as an ATD pin, reads of PTBD will return a 0 of the corresponding pin,
provided PTBDD is 0.
86
For port A pins that are outputs, these read/write control bits determine whether the slew rate
controlled outputs are enabled. For port A pins that are configured as inputs, these bits are ignored.
These read/write bits control the direction of port A pins and what is read for PTAD reads.

1 = Slew rate control enabled.
0 = Slew rate control disabled.
1 = Output driver enabled for port A bit n and PTAD reads return the contents of PTADn.
0 = Input (output driver disabled) and reads return the pin value.
