Table 1.1 : Port Mode Control Summary.
Mode 0 (unidirectional 8-bit mode)
Port A
Submode 00 - Pin-definable Double-buffered Input or Single-buffered Output
H1 - Latches Input Data
H2 - Status/interrupt Generating Input, General-purpose Output, or Operation with H1 in the Interlocked or
Pulsed Handshake Protocols
Submode 01 - Pin-definable Double-buffered Output or Non-latched Input
H1 - Indicates Data Received by Peripheral
H2 - Status/interrupt Generating Input, General-purpose Output, or Operation with H1 in the Interlocked or
Pulsed Handshake Protocols
Submode 1X - Pin-definable Single-buffered Output or non-latched Input
H1 - Status/interrupt Generating Input
H2 - Status/interrupt Generating Input or General-purpose Output
