Rev. 2.1
Function:
Alternate
Address:
Port E is a 3-bit special-function port that shares all of its pins with the
sync processor.
The port E data register contains a data latch for each of the three port E
pins.
PTE2–PTE0 — Port E Data Bits
VSYNCO — Vsync Output
HSYNC — Hsync Output
Reset:
Read:
Write:
PTE2–PTE0 are read/write, software programmable bits. Data
direction of each port E pin is under the control of the corresponding
bit in data direction register E.
The PTE2/VSYNCO pin is the Vsync output from the sync processor.
When the VSYNCOE is clear, the PTE2/VSYNCO pin is available for
general-purpose I/O. See
The PTE1/HSYNCO pin is the Hsync output from the sync processor.
When the HSYNCOE is clear, the PTE1/HSYNCO pin is available for
general-purpose I/O. See
