The following registers are described in Table 9-11 and in Table 9-12.
• PEDR—Port E data register. Reads value at pins. Writes to port E preload register.
• PEDDR—Port E data direction register. Set to "1" to make corresponding pin an out-
• PEFR—Port E function register. Set bit to "1" to make corresponding output an I/O
• PEBxR—These are individual registers to set individual output bits on or off.
• PECR—Parallel port E control register. This register is used to control the clocking of
