General Description
Pin Assignments
1.5.5 Port A Input/Output Pins (PTA7, PTA6/KBD6–PTA1/KBD1, and PTA0)
Port A is an 8-bit special function port that shares its pins with the
keyboard interrupt.
Six port A pins (PTA6–PTA1) can be programmed to serve as an
external interrupt. Once enabled, that pin will contain an internal pullup
resistor.
All port A pins are high-current sink pins.
1.5.6 Port B Input/Output Pins (PTB5, PTB4/TCH1, PTB3/TCLK, PTB2/TCH0,
PTB1, and PTB0/MCLK)
Port B is a 6-bit, general-purpose, bidirectional I/O port, with some of its
pins shared with the timer (TIM) module.
