参与上电复位的信号，低电平时有效，通知调制解调器或数据集就绪OK，多见于IO 芯片W83627EHF中的52脚DTRA#/GP64(PENROM)
官方原英文说明如下
UART A Data Terminal Ready. An active low signal informs the
modem or data set that the controller is ready to communicate.
During power-on reset, this pin is pulled down internally and is
defined as PENROM disable, which provides the power-on value
for CR24 bit 1 (ENROM). A 1 kΩ is reserved to pull down and a
1 kΩ resistor is recommended if intends to pull-up to enable
