UART1: URXD1, UTXD1

Reserved

In addition, the VDD3P3V_PWDN.TIMER1 field determines the power state of the Timer1 Block pins. The

Timer1 Block pins default to powered down and not operational. To use these pins, user must first

program

VDD3P3V_PWDN.TIMER1 field, see Section 3.2, Power Considerations.

The Timer1 Block features internal pull up resistors, which matches the UART inactive polarity.

Serial Port Block

This block of 12 pins consists of McASP0, McBSP0, McBSP1, and GPIO muxed pins. The following

•

PINMUX1.SPBK0

•

PINMUX1.SPBK1

The Serial Port Block is further subdivided into these sub-blocks:

•

Serial Port Sub-Block 0: McBSP0, part of McASP0, GPIO.

•

Serial Port Sub-Block 1: McBSP1, part of McASP0, GPIO.

Table 3-33 summarizes the 12 pins in the Serial Port Block, the multiplexed function on each pin, and the

PINMUX configurations to select the corresponding function.
