Control block/Data
Description
Related data
This data sets the general-purpose counter input pin (HCTR).
General-purpose counter measurement start data
CTE = 1: Count start
= 0: Count reset
This data determines the measurement time (frequency mode) and number of
periods (period mode) for the general-purpose counter.
CTP = 0: When a count reset is executed (CTE = 0), the general-purpose
counter input is pulled down.
= 1: When a count reset is executed (CTE = 0), the general-purpose
counter input is not pulled down, and the wait time is reduced.
However, immediately after CTP = 1 is set, the start of the count
must wait until the general purpose counter input pin is biased.
The input sensitivity is reduced when CTC = 1. (Sensitivity: 10 to 30 mVrms)
I/O port control data
This data specifies whether an I/O port is an input port or an output port.
“data”= 0: Input port
= 1: Output port
I/O-1 to I/0-2
* During a power-on reset, I/O-0 and I/O-2 become input ports.
STSD SW becomes an output port.
This data determines the status of the SEEK SW pin.
“data” = 0: 2.5[V] output
SEEK SW
* This pin is open and the midpoint bias is output by an external circuit.
“data” = 1: 0[V] or 5[V] output
* Determined by the OUT0 data.
AM/FM SD, FM-ST IND output dual-purpose pin
SDST SW
“data” = 0: Fixed
= 1: Prohibited
Output port data
This data determines the output on output ports O-0 through O-3.
“data” = 1: Open or Hi
OUT0 to OUT2
= 0: Low
* Invalid if specified as an input port or unlocked output.
This data converts the general-purpose counter pin to an input port.
HCTR = 0: Prohibited
= 1: HCTR (general-purpose counter)
