(6) High-impedance output control registers 00, 01, 10, 11, 20, 21 (HZAmCTL0, HZAmCTL1)
Note V850E/IA4 only
Caution High-impedance control is performed only when a port pin is set to function as indicated in the
Pins Subject to High-Impedance
The HZAmCTL0 and HZAmCTL1 registers are 8-bit registers that control the high-impedance state of the
output buffer.
These registers can be read or written in 8-bit or 1-bit units. However, the HZAmDCFn bit is a read-only bit
and cannot be written.
16-bit access is not possible.
Reset sets these registers to 00H.
The same value can be always rewritten to the HZAmCTLn register by software.
The relationship between detection factor and the control registers is shown below.
