// DANGER: Writing to PortD to (for example) toggle the serial enable bit has potential side effects.
// For example, if we |= or &= the serial enable bit (as PrvSerialEnable used to do) and inadvertently
// write other one-bits to portDData, we may clear pending edge interrupts on those other bits, like
// for example, the keyboard edge interrupt bits. Though the docs are somewhat ambiguous (surprise!),
// it would APPEAR that this is only the case for the keyboard interrupt bits (INT0-INT3). This DID
// cause problems when re-enabling the serial port during HwrWake->SerialWake, as it would clear any
// pending keyboard interrupts that woke the device (such as the power key or application buttons).
// SO, when writing to the serial enable bit, we MUST be sure to mask against hwrEZPortDDataMaskBeforeWrite
// before writing to portDData. This is ALSO VERY IMPORTANT for anyone who might make use of bit 6 (IRQ3)
// as an output pin. Whenever writing to hwrEZPortDFree3, one should always read portDData first, twiddle
// hwrEZPortDFree3 as appropriate, and with hwrEZPortDDataMaskBeforeWrite and finally write to portDData.
