Description

The SX48BD contains five 8-bit I/O ports (Port A through Port E). Port A provides symmetrical drive capability. In the 48-pin version of SX48BD, Port A has only four pins rather than eight. The unavailable pins are pulled high. Each port has four associated 8-bit registers (Direction, Data, TTL/CMOS Select, and Pull-Up Enable) to configure each port pin as Hi-Z input or output, to select TTL or CMOS voltage levels, and to enable/disable the weak pull-up resistor. The least significant bit of the registers corresponds to the least significant port pin. To access these configuration registers, an appropriate value must be written into the MODE register

SX48BD also supports the on-chip differential comparator. Ports RB1 and RB2 are the comparator negative and positive inputs, respectively, while Port RB0 is the comparator output pin. Port B also supports the Multi-Input  Wakeup feature on all eight pins.

SX48BD also support the multi-function timers T1 and T2. RB4 and RB5 are the T1 capture inputs, RB6 is the T1 PWM output, and RB7 is the T1 external event counter input. Similarly, RC0 and RC1 are the T2 capture inputs, RC2 is the T2 PWM output, and RC3 is the T2 external event counter input.
